Converting Carbon Dioxide into Useful Products

In my 19 December 2016 post, “What to do with Carbon Dioxide,” I provided an overview of the following three technologies being developed for underground storage (sequestration) or industrial utilization of carbon dioxide:

  • Store in basalt formations by making carbonate rock
  • Store in fractures in deep crystalline rock
  • Make ethanol

In the past two years, significant progress has been made in the development of processes to convert gaseous carbon dioxide waste streams into useful products.   This post is intended to highlight some of the advances being made and provide links to additional current sources of information on this subject.

1. Carbon XPrize:  Transforming carbon dioxide into valuable products

The NRG / Cosia XPrize is a $20 million global competition to develop breakthrough technologies that will convert carbon dioxide emissions from large point sources like power plants and industrial facilities into valuable products such as building materials, alternative fuels and other items used every day.  You’ll find details on this competition on the XPrize website at the following link:

https://www.xprize.org/prizes/carbon

As shown in the following timeline from the above website, this competition started in September 2015.

Carbon XPrize schedule

In April 2018, the following ten international teams were selected as finalists:

  • Four teams from Canada:  Carbicrete, Carbon Upcycling Technologies, CarbonCure and CERT
  • Three teams from USA:  C2CNT, Carbon Upcycling UCLA and Newlight
  • One team from UK:  Carbon Capture Machine
  • One team from India:  Breathe
  • One team from China:  C4X

The processes being developed by these teams will produce a range of valuable products:

You can read more about each of the competing teams and their intended products in the XPrize finalist selection report here:

https://assets-us-01.kc-usercontent.com/5cb25086-82d2-4c89-94f0-8450813a0fd3/ec5aba69-e68b-48c8-99b0-151e21749d67/XPRIZE%20Carbon%20Finalist%20Team%20Deck.pdf

The competition is now in the testing and certification phase.  Each team is expected to scale up their pilot systems by a factor of 10 for the operational phase, which starts in June 2019 at the Wyoming Integrated Test Center and the Alberta (Canada) Carbon Conversion Technology Center.  

The teams will be judged by the amount of carbon dioxide converted into usable products and the value of those products.  We’ll have to wait until the spring of 2020 for the results of this competition.

2. World’s largest post-combustion carbon capture project

Post-combustion carbon capture refers to capturing carbon dioxide from flue gas after a fossil fuel (e.g., coal, natural gas or oil) has been burned and before the flue gas is exhausted to the atmosphere.  You’ll find a 2016 review of post-combustion carbon capture technologies in the paper by Y. Wang, et al., “A Review of Post-combustion Carbon Dioxide  Capture Technologies from Coal-fired Power Plants,” which is available on the ScienceDirect website here:

https://reader.elsevier.com/reader/sd/pii/S1876610217313851?token=477195C9DBC9D5A1FCDBD7EB6CF04B595E1E377350690F4D2EC6E3D945DA570279962F3A75EE2B281A209A2F52B42A81

In January 2017, NRG Energy reported the completion of the Petra Nova post-combustion carbon capture project, which is designed to remove 90% of the carbon dioxide from a 240 MW “slipstream” of flue gas at the existing W. A. Parish generating plant Unit 8.  The “slipstream” represents 40% of the total flue gas flow from the coal-fired 610 MW Unit 8.  To date, this is the largest post-combustion carbon capture project in the world.  Approximately 1.4 million metric tons of carbon dioxide will be captured annually using a process jointly developed by Mitsubishi Heavy Industries, Ltd. (MHI) and the Kansai Electric Power Co.  The US Department of Energy (DOE) supported this project with a $190 million grant.

The DOE reported: “The project will utilize a proven carbon capture process, which uses a high-performance solvent for carbon dioxide absorption and desorption. The captured carbon dioxide will be compressed and transported through an 80 mile pipeline to an operating oil field where it will be utilized for enhanced oil recovery (EOR) and ultimately sequestered (in the ground).”

3. Pilot-scale projects to convert carbon dioxide to synthetic fuel

Thyssenkrupp pilot project for conversion of steel mill gases into methanol

In September 2018, Thyssenkrupp reported that it had “commenced production of the synthetic fuel methanol from steel mill gases. It is the first time anywhere in the world that gases from steel production – including the carbon dioxide they contain – are being converted into chemicals. The start-up was part of the Carbon2Chem project, which is being funded to the tune of around 60 million euros by Germany’s Federal Ministry of Education and Research (BMBF)……..‘Today the Carbon2Chem concept is proving its value in practice,’ said Guido Kerkhoff, CEO of Thyssenkrupp. ‘Our vision of virtually carbon dioxide-free steel production is taking shape.’”

Berkeley Laboratory developing a copper catalyst that yields high efficiency carbon dioxide-to-fuels conversion

The DOE Lawrence Berkeley National Laboratory (Berkeley Lab) has been engaged for many years in creating clean chemical manufacturing processes that can put carbon dioxide to good use.  In September 2017, Berkeley Lab announced that its scientists has developed a new electrocatalyst comprised of copper nanoparticles that can directly convert carbon dioxide into multi-carbon fuels and alcohols (e.g., ethylene, ethanol, and propanol) using record-low inputs of energy.  For more information, see the Global Energy World article here:

http://www.globalenergyworld.com/news/30336/copper_catalyst_yields_high_efficiency_co2-to-fuels_conversion.htm

4. Pilot-scale “Negative Emissions Technology” plants

The term negative emissions technology (NET) refers to an industrial processes designed to remove and sequester carbon dioxide directly from the ambient atmosphere rather than from a large point source of carbon dioxide generation (e.g. the flue gas from a fossil-fueled power generating station or a steel mill).  Think of a NET facility as a carbon dioxide removal “factory” that can be sited independently from the sources of carbon dioxide generation.

The Swiss firm Climeworks is in the business of developing carbon dioxide removal factories using the following process:

“Our plants capture atmospheric carbon with a filter. Air is drawn into the plant and the carbon dioxide within the air is chemically bound to the filter.  Once the filter is saturated with carbon dioxide it is heated (using mainly low-grade heat as an energy source) to around 100 °C (212 °F). The carbon dioxide is then released from the filter and collected as concentrated carbon dioxide gas to supply to customers or for negative emissions technologies.  Carbon dioxide-free air is released back into the atmosphere. This continuous cycle is then ready to start again. The filter is reused many times and lasts for several thousand cycles.”

This process is shown in the following Climeworks diagram:

You’ll find more information on Climeworks on their website here:

http://www.climeworks.com

Climeworks NET in Iceland

In 2017, Climeworks began operation in Iceland of their first pilot facility to remove carbon dioxide from ambient air and produce concentrated carbon dioxide that is injected into underground basaltic rock formations, where the carbon dioxide gets converted into carbonite minerals in a relatively short period of time (1 – 2 years) and remains fixed in the rock.  Climeworks uses waste heat from a nearby geothermal generating plant to help run their carbon capture system.  This process is shown in the following diagram.

Source: Climeworks

This small-scale pilot facility is capable of removing only about 50 tons of carbon dioxide from the atmosphere per year, but can be scaled up to a much larger facility.  You’ll find more information on this Climeworks project here:

https://www.popularmechanics.com/science/green-tech/news/a28629/first-negative-emissions-plant/

Climeworks NET in Italy

In October 2018, Climeworks began operation in Italy of another pilot-scale NET facility designed to remove carbon dioxide from the atmosphere.  This facility is designed to remove 150 tons of carbon dioxide from the atmosphere per year and produce a natural gas product stream from the atmospheric carbon dioxide, water, and electricity.  You’ll find more information on this Climeworks project here:

https://www.popularmechanics.com/science/green-tech/a23621438/climeworks-co2-methane-facility/

5. Consensus reports on waste stream utilization and negative emissions technologies (NETs)

The National Academies Press (NAP) recently published a consensus study report entitled, “Gaseous Carbon Waste Streams Utilization, Status and Research Needs,”  which examines the following processes:

  • Mineral carbonation to produce construction material
  • Chemical conversion of carbon dioxide into commodity chemicals and fuels
  • Biological conversion (photosynthetic & non-photosynthetic) of carbon dioxide into commodity chemicals and fuels
  • Methane and biogas waste utilization

The authors note that, “previous assessments have concluded that …… > 10 percent of the current global anthropogenic carbon dioxide emissions….could feasibly be utilized within the next several decades if certain technological advancements are achieved and if economic and political drivers are in place.”

https://www.nap.edu/catalog/25232/gaseous-carbon-waste-streams-utilization-status-and-research-needs

Also on the NAP website is a prepublication report entitled, “Negative Emissions Technologies and Reliable Sequestration.” The authors note that NETs “can have the same impact on the atmosphere and climate as preventing an equal amount of carbon dioxide from being emitted from a point source.”

Source: National Academies Press

You can download a free pdf copy of this report here:

https://www.nap.edu/catalog/25259/negative-emissions-technologies-and-reliable-sequestration-a-research-agenda

In this report, the authors note that recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions at the source, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. “ For example, NAPs could be a means for mitigating the methane generated from enteric fermentation in the digestive systems of very large numbers of ruminant animals (e.g., in the U.S., primarily beef and dairy cattle).  For more information on this particular matter, please refer to my 31 December 2016 post, “Cow Farts Could be Subject to Regulation Under a New California Law,” which you’ll find here:

What’s been happening in your neighborhood for the past 750 million years?

A 15 February 2019 article by Meilan Solly in the Smithsonian online magazine describes a recently released interactive map of the world that shows how the Earth’s continents have moved since 750 million years ago.   With your cursor, you can zoom in and rotate the globe in any direction. Using a pull-down menu at the top center of the screen, you can see the relative positioning of the landmasses at the point in time you selected.  A similar selection box in the upper right corner of the screen allows you to select a particular geological or evolutionary milestone (i.e., first land animals) in Earths’ development.  Even better, you can enter an address in the text box in the upper-left corner of the screen and then see how your selected location has migrated as you explore through the ages.

The Next Phase in the Hunt for New Superheavy Elements is About to Start

Background

On 24 January 2016, I posted the article, “Where in the Periodic Table Will We Put Element 119?”, which reviews the development of the modern periodic table of chemical elements since it was first formulated in 1869 by Russian chemist Dimitri Mendeleev, through the completion of Period 7 with the naming element 118 in 2016.  You can read this post here:

https://lynceans.org/all-posts/where-in-the-periodic-table-will-we-put-element-119/

2019 is the 150thanniversary of Dimitri Mendeleev’s periodic table of elements.  To commemorate this anniversary, the United Nations General Assembly and the United Nations Educational, Scientific and Cultural organization (UNESCO) have proclaimed 2019 as the International Year of the Periodic Table of Chemical Elements (IYPT). You’ll find more information on the IYPT here:

https://www.iypt2019.org

A brief animated “visualization” entitled “Setting the Table,”created by J. Yeston, N. Desai and E. Wang, provides a good overview of the history and configuration of the periodic table.  Check it out here:

http://vis.sciencemag.org/periodic-table/

The prospects for extending the periodic table beyond element 118 (into a new Period 8) is discussed in a short 2018 video from Science Magazine entitled “Where does the periodic table end?,”which you can view here:

https://www.sciencemag.org/news/2019/02/where-does-periodic-table-end?utm_campaign=news_weekly_2019-02-01&et_rid=215579562&et_cid=2632608

The next phase in the hunt for new superheavy elements is about to start in Russia 

Flerov Laboratory of Nuclear Reactions (FLNR) Joint Institute for Nuclear Research (JINR) in Dubna is the leading laboratory in Russia, and perhaps the world, in the search for superheavy elements.  The FLNR website is here:

http://flerovlab.jinr.ru/flnr/she_factory_no.html

FLNR is the home of several accelerators and other experimental setups for nuclear research, including the U400 accelerator, which has been the laboratory’s basic tool for the synthesis of new elements since being placed in operation in 1979.  You can take a virtual tour of U400 on the FLNR website.  

On 30 May 2012 the International Union of Pure and Applied Chemistry (IUPAC) honored the work done by FLNR when it approved the name Flerovium (Fl) for superheavy element 114.

Yuri Oganessian, the Scientific Leader of FLNR, has contributed greatly to extending the periodic table through the synthesis of new superheavy elements.  On 30 November 2016, IUPAC recognized his personal contributions by naming superheavy element 118 after him:  Oganesson (Og).

FLNR has built a new $60 million accelerator facility, dubbed the Superheavy Element Factory (SHEF), which is expected to be capable of synthesizing elements beyond 118.  The SHEF building and the DC-280 cyclotron that will be used to synthesize superheavy elements are shown in the photos below.

The 2016 paper, “Status and perspectives of the Dubna superheavy element factory,”by S. Dmitriev, M. Itkis and Y. Oganessian, presents an overview of the DC-280 cyclotron design, including the following diagram showing the general arrangement of the major components.

For insights into the processes for synthesizing superheavy elements, I recommend that you view the following March 2018 video in which FLNR Director Sergey Dmitriev describes the design of SHEF and the planned process of synthesizing superheavy elements 119 and 120.  This is a rather long (23 min) video, but I think it will be worth your time.

On 26 December 2018, the DC-280 cyclotron produced its first beam of accelerated heavy ions.  The hunt for new superheavy elements using DC-280 is scheduled to begin in the spring of 2019.

A good overview of FLNR, as it prepares to put its Superheavy Element Factory into operation, is available in the article by Sam Kean, entitled “A storied Russian lab is trying to push the periodic table past its limits—and uncover exotic new elements,” which was posted on 30 January 2019 on the Science Magazine website. You’ll find this article at the following link:

The next few years may yield exciting new discoveries of the first members of Period 8 of the periodic table.  I think Dimitri Mendeleev would be impressed.

Worldwide Gross Domestic Product (GDP) Trends, 1960 – 2017, and Projections, 2018 – 2100

Ian Fraser is an award-winning journalist, commentator and broadcaster who writes about business, finance, politics and economics.  In 2018, under the banner of WawamuStats, he started posting a series of short videos that help visualize trends that are hard to see in voluminous numerical data, but become apparent (even a bit stunning) in a dynamic graphical format.  On its Facebook page, WawamuStats explains:

“Historical data are fun, but reading them is tedious. This page makes these tedious data into a dynamic timeline, which shows historical data.”

Regarding the GDP data used for the dynamic visualizations, WawamuStats states:

“Gross Domestic Product (GDP) is a monetary measure of the market value of all the final goods and services produced in a period of time, often annually or quarterly. Nominal GDP estimates are commonly used to determine the economic performance of a whole country or region, and to make international comparisons.”

Here are the three WawamuStats GDP videos I think you will enjoy.

Top 10 Country GDP Ranking History (1960-2017)

This dynamic visualization shows the top 10 countries with the highest GDP from 1960 to 2017.  At the start, most of the top 10 countries are from Europe and North America. You’ll see the rapid rise of Japan’s economy followed decades later by the rapid rise of China’s economy.

Top 10 Country GDP Per Capita Ranking History (1962-2017)

This dynamic visualization shows the top 10 countries with the highest GDP per capita from 1962 to 2017.  As you will see, most of the top 10 countries are from developed regions in Europe, North America, and Asia. Since 2017, Luxembourg has been regarded as the richest country in terms of GDP per capita.

Future Top 10 Country Projected GDP Ranking (2018-2100)

This dynamic visualization shows how Asian economies are expected to grow and eventually dominate the world economy, with China’s economy, and later India’s economy, exceeding the US economy in terms of GDP, and several European economies dropping out of the top 10 ranking. While the specific national GDP values are only projections, the macro trends, with a strong shift toward Asian economies, probably is correct.

Ultima Thule – The First Visit to a Kuiper Belt Object at the Fringe of Our Solar System

The National Aeronautics and Space Administration’s (NASA) durable New Horizon spacecraft made its close flyby of Pluto on 14 July 2015, passing 7,800 mi (12,500 km) above the surface of that dwarf planet and returning a remarkable trove of photos and data.  Since then, the spacecraft has been continuing its journey out of our solar system and now is flying through the Kuiper Belt, which is a very large, diffuse region beyond the orbit of Neptune containing millions of small bodies in distant orbits around the Sun.  These Kuiper Belt Objects (KBOs) are believed to be “leftovers” (i.e., they never coalesced into planets) from the formation of the early solar system.  You can read more about the Kuiper Belt on the NASA website here:

https://solarsystem.nasa.gov/solar-system/kuiper-belt/overview/

On 28 August 2015, NASA announced that it had selected the next destination for New Horizons after the Pluto flyby: a small KBO designated 2014 MU69, now commonly known as Ultima Thule, about 1 billion miles (1.6 billion km) beyond Pluto.  The spacecraft’s trajectory from Earth to Ultima Thule is shown in the following NASA diagram.

Source: NASA, Johns Hopkins University Applied Physics Lab, Southwest Research Institute

On 1 January 2019, the New Horizons spacecraft made a close flyby of Ultima Thule, at a range of 2,200 miles (3,500 km) and a relative speed of 14 kilometers per second (31,317 mph). At a distance of 4.1 billion miles (6.6 billion km) from the Earth, radio signals took 6 hours and 6 minutes traveling at the speed of light to traverse the distance between the spacecraft and Earth during the encounter. On 1 January 2019, NASA released the following blurry image, which was taken at long range.

NASA reported: “At left is a composite of two images taken by New Horizons’ high-resolution Long-Range Reconnaissance Imager (LORRI), which provides the best indication of Ultima Thule’s size and shape so far. Preliminary measurements of this Kuiper Belt object suggest it is approximately 20 miles long by 10 miles wide (32 kilometers by 16 kilometers). An artist’s impression at right illustrates one possible appearance of Ultima Thule, based on the actual image at left. The direction of Ultima’s spin axis is indicated by the arrows. “

In the weeks following the flyby, New Horizons will be downloading all of the higher-resolution photos and data acquired during its close encounter with Ultima Thule and we’ll be getting a much more detailed understanding of this KBO. 

It appears that NASA has the opportunity to target one or more additional KBOs for future New Horizons flybys in the 2020s.  The spacecraft’s electric power source, a plutonium (Pu-238)-fueled radioisotope thermoelectric generator (RTG), is capable of providing power well into the 2030s, albeit at gradually reducing power levels.  In addition, the spacecraft has significant hydrazine fuel remaining for course correction and attitude control en route to a future KBO flyby.

2 January 2019 Update: NASA released a new photo taken on the inbound leg of the flyby, still 18,000 miles (28,000 km) from Ultima Thule

NASA reported: “This image taken by the Long-Range Reconnaissance Imager (LORRI) is the most detailed of Ultima Thule returned so far by the New Horizons spacecraft. It was taken at 5:01 Universal Time on January 1, 2019, just 30 minutes before closest approach from a range of 18,000 miles (28,000 kilometers)…”

24 January 2019 Update:  Latest photo shows Ultima Thule surface to be unusually smooth

Today, NASA released the following photo of Ultima Thule, taken at a distance of 4,200 miles (6,700 kilometers) on 1 January 2019, just seven minutes before closest approach.  Principal Investigator Alan Stern, of the Southwest Research Institute, reported, “Over the next month there will be better color and better resolution images that we hope will help unravel the many mysteries of Ultima Thule.”

75th Anniversary of the US Nuclear Weapons Complex

1.  Background

On 19 January 1942, US President Franklin D. Roosevelt approved the production of an atomic bomb.  At that time, most of the technology for producing an atomic bomb still needed to be developed and the US had very little infrastructure in place to support that work.

The Manhattan Engineer District (MED, aka the “Manhattan Project”) was responsible for the research, design, construction and operation of the early US nuclear weapons complex and for delivering atomic bombs to the US Army during World War II (WW II) and in the immediate post-war period.  The Manhattan Project existed for just five years. In 1943, 75 years ago, the Manhattan Project transitioned from planning to construction and initial operation of the first US nuclear weapons complex facilities.   Here’s a very brief timeline for the Manhattan Project.

  • 13 August 1942: The Manhattan Engineer District was formally created under the leadership of U.S. Army Colonel Leslie R. Groves.
  • 2 December 1942: A team led by Enrico Fermi achieved the world’s first self-sustaining nuclear chain reaction in a graphite-moderated, natural uranium fueled reactor known simply as Chicago Pile-1 (CP-1).
  • 1943 – 1946: The Manhattan Project managed the construction and operation of the entire US nuclear weapons complex.
  • 16 July 1945: The first nuclear device was successfully tested at the Trinity site near Alamogordo, NM, less than three years after the Manhattan Project was created.
  • 6 & 9 August 1945:  Atomic bombs were employed by the US against Japan, contributing to ending World War II.
  • 1 January 1947:  The newly formed, civilian-led Atomic Energy Commission (AEC) took over management and operation of all research and production facilities from the Manhattan Engineer District.
  • 25 August 1947: The Manhattan Engineer District was abolished.

The WW II nuclear weapons complex was the foundation for the early US post-war nuclear weapons infrastructure that evolved significantly over time to support the US mutually-assured destruction strategy during the Cold War with the Soviet Union.  Today, the US nuclear weapons complex continues to evolve as needed to perform its critical role in maintaining the US nuclear deterrent capability.

3.  The Manhattan Project National Historical Park

The Manhattan Project National Historical Park was authorized by Congress in December 2014 and subsequently was approved by the President to commemorate the Manhattan Project. The Manhattan Project National Historical Park is an extended “park” that currently is comprised of three distinct DOE sites that each had different missions during WW II: 

  • Los Alamos, New Mexico: Nuclear device design, test and production
  • Oak Ridge, Tennessee: Enriched uranium production
  • Hanford, Washington: Plutonium production

On 10 November 2015, a memorandum of agreement between DOE and the National Park Service (NPS) established the park and the respective roles of DOE and NPS in managing the park and protecting and presenting certain historic structures to the public.

You’ll find the Manhattan Project National Historical Park website here: 

https://manhattanprojectnationalpark.com

Following is a brief overview of the three sites that currently comprise the Manhattan Project National Historical Park.

3.1. Los Alamos, New Mexico

Los Alamos Laboratory was established 75 years ago, in early 1943, as MED Site Y, under the direction of J. Robert Oppenheimer. This was the Manhattan Project’s nuclear weapons laboratory, which was created to consolidate in one secure, remote location most of the research, design, development and production work associated producing usable nuclear weapons to the US Army during WW II.

The first wave of scientists began arriving at Los Alamos Laboratory in April 1943.  Just 27 months later, on 16 July 1945, the world’s first nuclear device was detonated 200 miles south of Los Alamos at the Trinity Site near Alamogordo, NM.  This was the plutonium-fueled, implosion-type device code named “Gadget.”  

During WW II, the Los Alamos Laboratory produced three atomic bombs:

  • One uranium-fueled, gun-type atomic bomb code named “Little Boy” was produced. This was the atomic bomb dropped on Hiroshima, Japan on 6 August 1945, making it the first nuclear weapon used in warfare.  This atomic bomb design was not tested before it was used operationally.
  • Two plutonium-fueled, implosion-type atomic bombs code named “Fat Man” were produced.  These bombs were very similar to Gadget.  One of the Fat Man bombs was dropped on Nagasaki, Japan on 9 August 1945.  The second Fat Man bomb could have been used during WW II, but it was not needed after Japan announced its surrender on 15 August 1945.

The highly-enriched uranium for the Little Boy bomb was produced by the enrichment plants at Oak Ridge.  The plutonium for Gadget and the two Fat Man bombs was produced by the production reactors at Hanford.

Three historic sites are on Los Alamos National Laboratory property and currently are not open to the public:

  • Gun Site Facilities: three bunkered buildings (TA-8-1, TA-8-2, and TA-8-3), and a portable guard shack (TA-8-172).
  • V-Site Facilities: TA-16-516 and TA-16-517 V-Site Assembly Building
  • Pajarito Site: TA-18-1 Slotin Building, TA-8-2 Battleship Control Building, and the TA-18-29 Pond Cabin.

3.2. Oak Ridge, Tennessee

Land acquisition was approved in 1942 for planned uranium “atomic production plants” in the Tennessee Valley.  The selected site officially became the Clinton Engineer Works (CEW) in January 1943 and was given the MED code name Site X.  This is where MED and its contractors managed the deployment during WW II of the following three different uranium enrichment technologies in three separate, large-scale industrial process facilities:  

  • Liquid thermal diffusion process, based on work by Philip Abelson at Naval Research Laboratory and the Philadelphia Naval Yard.  This process was implemented at S-50, which produced uranium enriched to < 2 at. % U-235.
  • Gaseous diffusion process, based on work by Harold Urey at Columbia University.  This process was implemented at K-25, which produced uranium enriched to about 23 at. % U-235 during WW II. 
  • Electromagnetic separation process, based on Ernest Lawrence’s invention of the cyclotron at the University of California Berkeley in the early 1930s.  This process was implemented at Y-12 where the final output was weapons-grade uranium.  

The Little Boy atomic bomb used 92.6 pounds (42 kg) of highly enriched uranium produced at Oak Ridge with contributions from all three of these processes.

The nearby township was named Oak Ridge in 1943, but the nuclear site itself was not officially renamed Oak Ridge until 1947.

The three Manhattan Project National Historical Park sites at Oak Ridge are:

  • X-10 Graphite Reactor National Historic Landmark
  • K-25 complex
  • Y-12 complex: Buildings 9731 and 9204-3 

The S-50 Thermal Diffusion Plant was dismantled in the late 1940s. This site is not part of the Manhattan Project National Historical Park.

Following is a brief overview of X-10, K-25 and Y-12 historical sites. There’s much more information on the Manhattan Project National Historical Park sites at Oak Ridge here:

X-10 Graphite Reactor

X-10 was the world’s second nuclear reactor (after the Chicago Pile, CP-1) and the first reactor designed and built for continuous operation. It was intended to produce the first significant quantities of plutonium, which were used by scientists at Los Alamos to characterize plutonium and develop the design of a plutonium-fueled atomic bomb.  

X-10 was a large graphite-moderated, natural uranium fueled reactor that originally had an continuous design power rating of 1.0 MWt, which later was raised to 3.5 MWt. Originally, it was intended to be a prototype for the much larger plutonium production reactors being planned for Hanford.  The selection of air cooling for X-10 enabled this reactor to be deployed more rapidly, but limited its value as a prototype for the future water-cooled plutonium production reactors.

The X-10 reactor core was comprised of graphite blocks arranged into a cube measuring 24 feet (7.3 meters) on each side.  The core was surrounded by several feet of high-density concrete and other material to provide radiation shielding.  The core and shielding were penetrated by 1,248 horizontal channels arranged in 36 rows. Each channel served to position up to 54 fuel slugs in the core and provide passages for forced air cooling of the core. Each fuel slug was an aluminum clad, metallic natural uranium cylinder measuring 4 inches (10.16 cm) long x 1.1 inches (2.79 cm) in diameter.  New fuel slugs were added manually at the front face (the loading face) of the reactor and irradiated slugs were pushed out through the back face of the reactor, dropping into a cooling water pool.  The reactor was controlled by a set of vertical control rods.

The basic geometry of the X-10 reactor is shown below.

Site construction work started 75 years ago, on 27 April 1943. Initial criticality occurred less than seven months later, on 4 November 1943.  

Plutonium was recovered from irradiated fuel slugs in a pilot-scale chemical separation line at Oak Ridge using the bismuth phosphate process.  In April 1944, the first sample (grams) of reactor-bred plutonium from X-10 was delivered to Los Alamos.  Analysis of this sample led Los Alamos scientists to eliminate one candidate plutonium bomb design (the “Thin Man” gun-type device) and focus their attention on the Fat Man implosion-type device. X-10 operated as a plutonium production reactor until January 1945, when it was turned over to research activities.  X-10 was permanently shutdown on 4 November 1963, and was designated a National Historic Landmark on 15 October 1966.

K-25 Gaseous Diffusion Plant

Preliminary site work for the K-25 gaseous diffusion plant began 75 years ago, in May 1943, with work on the main building starting in October 1943. The six-stage pilot plant was ready for operation on 17 April 1944.  

K-25 site circa 1944.  Source: http://k-25virtualmuseum.org/timeline/index.html

The K-25 gaseous diffusion plant feed material was uranium hexafluoride gas (UF6) from natural uranium and slightly enriched uranium from both the S-50 liquid thermal diffusion plant and the first (Alpha) stage of the Y-12 electromagnetic separation plant.  During WW II, the K-25 plant was capable of producing uranium enriched up to about 23 at. % U-235.  This product became feed material for the second (Beta) stage of the Y-12 electromagnetic separation process, which continued the enrichment process and produced weapons-grade U-235.

As experience with the gaseous diffusion process improved and additional cascades were added, K-25 became capable of delivering highly-enriched uranium after WW II.

You can take a virtual tour of K-25, including its decommissioning and cleanup, here:

http://www.k-25virtualmuseum.org

Construction on the second Oak Ridge gaseous diffusion plant, K-27, began on 3 April 1945.  This plant became operational after WW II.  By 1955, the K-25 complex had grown to include gaseous diffusion buildings K-25, K-27, K-29, K-31 and K-33 that comprised a multi-building, enriched uranium production chain collectively known as the Oak Ridge Gaseous Diffusion Plant (ORGDP). Operation of the ORGDP continued until 1985.

Additional post-war gaseous diffusion plants based on the technology developed at Oak Ridge were built and operated in Paducah, KY (1952 – 2013) and Portsmouth, OH (1954 – 2001).

Y-12 Electromagnetic Separation Plant

In 1941, Earnest Lawrence modified the 37-inch (94 cm) cyclotron in his laboratory at the University of California Berkeley to demonstrate the feasibility of electromagnetic separation of uranium isotopes using the same principle as a mass spectrograph.

The initial industrial-scale design agreed in 1942 was called an Alpha (α) calutron, which was designed to enrich natural uranium (@ 0.711 at.% U-235) to >10 at.% U-235.  The later Beta (β) calutron was designed to further enrich the output of the Alpha calutrons, as well as the outputs from the K-25 and S-50 processes, and produce weapons-grade uranium at >88 at.% U-235.

The calutrons required large magnet coils to establish the strong electromagnetic field needed to separate the uranium isotopes U-235 and U-238. The shape of the magnet coils for both the Alfa and Beta calutrons resembled a racetrack, with many individual calutron modules (aka “tanks”) arranged side-by-side around the racetrack.  At Y-12, there were nine Alpha calutron “tracks” (5 x Alpha-1 and 4 x Alpha-2 tracks), each with 96 calutron modules (tanks), for a total of 864 Alpha calutrons.  In addition, there were eight Beta calutron tracks, each with 36 calutron modules, for a total of 288 beta calutrons, only 216 of which ever operated.

Due to wartime shortages of copper, the Manhattan Project arranged a loan from the Treasury Department of about 300 million Troy ounces (10,286 US tons) of silver for use in manufacturing the calutron magnet coils. A general arrangement of a Beta calutron module (tank) is shown in the following diagram, which also shows the isotope flight paths from the uranium tetrachloride  (UCl4) ion source to the ion receivers.  Separated uranium was recovered by burning the graphite ion receivers and extracting the metallic uranium from the ash.

Construction of Buildings 9731 and 9204-3 at the Y-12 complex began 75 years ago, in February 1943.  By February 1944, initial operation of the Alpha calutrons had produced only 0.44 pounds (0.2 kg) of U-235 @ 12 at.%. By August 1945, the Y-12 Beta calutrons had produced the 92.6 pounds (42 kg) of weapons-grade uranium needed for the Little Boy atomic bomb.

After WW II, the silver was recovered from the calutron magnet coils and returned to the Treasury Department.

3.3. Hanford, Washington

On January 16, 1943, General Leslie Groves officially endorsed Hanford as the proposed plutonium production site, which was given the MED code name Site W. The plan was to construct three large graphite-moderated, water-cooled plutonium production reactors, designated B, D, and F, in along the Columbia River.  The Hanford site also would include a facility for manufacturing the new uranium fuel slugs for the reactors as well as chemical separation plants and associated facilities to recover and process plutonium from the irradiated uranium slugs.

After WW II, six more plutonium production reactors were built at Hanford along with additional plutonium and nuclear waste processing and storage facilities.

The Manhattan Project National Historical Park sites at Hanford are:

  • B Reactor, which has been a National Historic Landmark since 19 August 2008
  • The previous Hanford High School in the former Town of Hanford and Hanford Construction Camp Historic District
  • Bruggemann’s Agricultural Warehouse Complex
  • White Bluffs Bank and Hanford Irrigation District Pump House

A brief overview of the B Reactor and the other Hanford production reactors is provided below.  There’s more information on the Manhattan Project National Historical Park sites at Hanford here:

The Manhattan Project National Historical Park does not include the Hanford chemical separation plants and associated plutonium facilities in the 200 Area, the uranium fuel production plant in the 300 Area, or the other eight plutonium production reactors that were built in the 100 Area. Information on all Hanford facilities, including their current cleanup status, is available on the Hanford website here:

https://www.hanford.gov/page.cfm/ProjectsFacilities

B Reactor

The B Reactor at the Hanford Site was the world’s first full-scale reactor and the first of three plutonium production reactor of the same design that became operational at Hanford during WW II.  B Reactor and the similar D and F Reactors were significantly larger graphite-moderated reactor than the X-10 Graphite Reactor at Oak Ridge.  The rectangular reactor core measured 36 feet (11 m) wide x 36 feet (11 m) tall x 28 feet (8.53 m) deep, surrounded by radiation shielding. These reactors were fueled by aluminum clad, metallic natural fuel slugs measuring 8 inches (20.3 cm) long x 1.5 inches (3.8 cm) in diameter.  As with the X-10 Graphite Reactor, new fuel slugs were inserted into process tubes (fuel channels) at the front face of the reactor. The irradiated fuel slugs were pushed out of the fuel channels at the back face of the reactor, falling into a water pool to allow the slugs to cool before further processing for plutonium recovery.

Reactor cooling was provided by the once-through flow of filtered and processed fresh water drawn from the Columbia River.  The heated water was discharged from the reactor into large retention basins that allowed some cooling time before the water was returned to the Columbia River.

Construction of B Reactor began 75 years ago, in October 1943, and fuel loading started 11 months later, on September 13, 1944.  Initial criticality occurred on 26 September 1944, followed shortly by operation at the initial design power of 250 MWt.

B Reactor was the first reactor to experience the effects of xenon poisoning due to the accumulation of Xenon (Xe-135) in the uranium fuel. Xe-135 is a decay product of the relatively short-lived (6.7 hour half-life) fission product iodine I-135.  With its very high neutron cross-section, Xe-135 absorbed sufficient neutrons to significantly, and unexpectedly, reduce B Reactor power. Fortunately, DuPont had added more process tubes (a total of 2004) than called for in the original design of B Reactor. After the xenon poisoning problem was understood, additional fuel was loaded, providing the core with enough excess reactivity to override the neutron poisoning effects of Xe-135.

On 3 February 1945, the first batch of B Reactor plutonium was delivered to Los Alamos, just 10 months after the first small plutonium sample from the X-10 Graphite Reactor had been delivered.

Regular plutonium deliveries from the Hanford production reactors provided the plutonium needed for the first ever nuclear device (the Gadget) tested at the Trinity site near Alamogordo, NM on 16 July 1945, as well as for the Fat Man atomic bomb dropped on Nagasaki, Japan on 9 August 1945 and an unused second Fat Man atomic bomb. These three devices each contained about 13.7 pounds (6.2 kilograms) of weapons-grade plutonium produced in the Hanford production reactors.

From March 1946 to June 1948, B Reactor was shut down for maintenance and modifications.  In March 1949, B Reactor began the first tritium production campaign, irradiating targets containing lithium and producing tritium for hydrogen bombs.  

By 1963, B Reactor was permitted to operate at a maximum power level of 2,090 MWt.  B Reactor continued operation until 29 January 1968, when it was ordered shut down by the Atomic Energy Commission.  Because of its historical significance, B Reactor was given special status that allows it to be open for public tours as part of the Manhattan Project National Historical Park.

The Other WW II Production Reactors at the Hanford Site:  D & F

During WW II, three plutonium reactors of the same design were operational at Hanford: B, D and F.  All had an initial design power rating of 250 MWt and by 1963 all were permitted to operate at a maximum power level of 2,090 MWt.

  • D Reactor:  This was the world’s second full-scale nuclear reactor.  It became operational in December 1944, but experienced operational problems early in life due to growth and distortion of its graphite core.  After developing a process for controlling graphite distortion, D Reactor operated successfully through June 1967.
  • F Reactor:  This was the third of the original three production reactors at Hanford.  It became operational in February 1945 and ran for more than twenty years until it was shut down in June1965.

D and F Reactors currently are in “interim safe storage,” which commonly is referred to as “cocooned.”  These reactor sites are not part of the Manhattan Project National Historical Park.

Post-war Production Reactors at Hanford: H, DR, C, K-West, K-East & N

After WW II, six additional plutonium production reactors were built and operated at Hanford. The first three, named H, DR and C, were very similar in design to the B, D and F Reactors.  The next two, K-West and K-East, were of similar design, but significantly larger than their predecessors.  The last reactor, named N, was a one-of-a kind design.

  • H Reactor:  This was the first plutonium production reactor built at Hanford after WW II. It became operational in October 1949 with a design power rating of 400 MWt and by 1963 was permitted to operate at a maximum power level of 2,090 MWt. It operated for 15 years before being permanently shut down in April 1965.
  • DR Reactor:  This reactor originally was planned as a replacement for the D Reactor and was built adjacent to the D Reactor site. DR became operational in October 1950 with an initial design power rating of 250 MWt. It operated in parallel with D Reactor for 14 years, and by 1963 was permitted to operate at the same maximum power level of 2,090 MWt.  DR was permanently shut down in December 1964.
  • C Reactor:  Reactor construction started June 1951 and it was completed in November 1952, operating initially at a design power of 650 MWt. By 1963, C Reactor was permitted to operate at a maximum power level of 2,310 MWt.  It operated for sixteen years before being shut down in April 1969.  C Reactor was the first reactor at Hanford to be placed in interim safe storage, in 1998.
  • K-West & K-East Reactors:  These larger reactors differed from their predecessors mainly in the size of the moderator stack, the number, size and type of process tubes (3,220 process tubes), the type of shielding and other materials employed, and the addition of a process heat recovery system to heat the facilities.  These reactors were built side-by-side and became operational within four months of each other in 1955: K-West in January and K-East in April.  These reactors initially had a design power of 1,800 MWt and by 1963 were permitted to operate at a maximum power level of 4,400 MWt before an administrative limit of 4,000 MWt was imposed by the Atomic Energy Commission. The two reactors ran for more than 15 years.  K-West was permanently shut down in February 1970 followed by K-East in January 1971.
  • N Reactor:  This was last of Hanford’s nine plutonium production reactors and the only one designed as a dual-purpose reactor capable of serving as a production reactor while also generating electric power for distribution to the external power grid.  The N Reactor had a reactor design power rating of 4,000 MWt and was capable of generating 800 MWe. The N Reactor also was the only Hanford production reactor with a closed-loop primary cooling system.  Plutonium production began in 1964, two years before the power generating part of the plant was completed in 1966.  N Reactor operated for 24 years until 1987, when it was shutdown for routine maintenance.  However, it never restarted, instead being placed in standby status by DOE and then later retired.

Four of these reactors (H, DR, C and N) are in interim safe storage while the other two (K-West and K-East) are being prepared for interim safe storage.  None of these reactor sites are part of the Manhattan Project National Historical Park.

The Federation of American Scientists (FAS) reported that the nine Hanford production reactors produced 67.4 metric tons of plutonium, including 54.5 metric tons of weapons-grade plutonium, through 1987 when the last Hanford production reactor (N Reactor) was shutdown.

75th Anniversary of the Kurchatov Institute

The I. V. Kurchatov Institute of Atomic Energy in Moscow was founded 75 years ago, in 1943, and is named for its founder, Soviet nuclear physicist Igor Vasilyevich Kurchatov.  Until 1955, the Institute was a secret organization known only as “Laboratory No. 2 of the USSR Academy of Sciences.”  The initial focus of the Institute was the development of nuclear weapons.

Kurchatov Institute 75thanniversary on Russian commemorative postage stamp. https://en.wikipedia.org/

I. V. Kurchatov and the team of scientists and engineers at the Institute led or supported many important historical Soviet nuclear milestones, including: 

  • 25 December 1946: USSR’s F-1 (Physics-1) reactor achieved initial criticality at Kurchatov Institute.  This was the 1st reactor built and operated outside the US.
  • 10 June 1948: USSR’s 1st plutonium production reactor achieved initial criticality (Unit A at Chelyabinak-65). The reactor was designed under the leadership of N. A. Dollezhal.
  • 29 August 1949: USSR’s 1st nuclear device, First Lightning [aka RDS-1, Izdeliye 501 (device 501) and Joe 1], was detonated at the Semipalatinsk test site in what is now Kazakhstan.  This was the 1st nuclear test other than by the US.
  • 27 June 1954: World’s 1st nuclear power plant, AM-1 (aka APS-1), was commissioned and connected to the electrical grid, delivering power in Obninsk.  AM-1 was designed under the leadership of N. A. Dollezhal.
  • 22 November 1955: USSR’s 1st thermonuclear device (RDS-37, a two-stage device) was detonated at the Semipalatinsk test site.  This also was the world’s 1stair-dropped thermonuclear device.
  • 5 December 1957: USSR’s 1st nuclear-powered icebreaker, Lenin, was launched.  This also was the world’s 1st nuclear-powered surface ship.
  • 4 July 1958: USSR’s 1st  nuclear-powered submarine, Project 627 SSN K-3, Leninskiy Komsomol, made its 1st underway on nuclear power.
  • 1958: World’s 1st Tokamak, T-1, initial operation at Kurchatov Institute.

I. V. Kurchatov served as the Institute’s director until his death in 1960 and was awarded Hero of Socialist Labor three times and Order of Lenin five times during his lifetime.

After I. V. Kurchatov’s death in 1960, the noted academician Anatoly P. Aleksandrov was appointed as the director of the Institute and continued in that role until 1989.  Aleksandrov already had a key role at the Institute, having been appointed by Stalin in September 1952 as the scientific supervisor for developing the USSR’s first nuclear-powered submarine and its nuclear power unit.

Until 1991, the Soviet Ministry of Atomic Energy oversaw the administration of Kurchatov Institute.  After the formation of the Russian Federation at the end of 1991, the Institute became a State Scientific Center reporting directly to the Russian Government.  Today, the President of Kurchatov Institute is appointed by the Russian Prime Minister, based on recommendations from Rosatom (the Russian State Energy Corporation), which was formed in 2007.

You’ll find a comprehensive history of Kurchatov Institute in a 2013 (70thanniversary) special issue of the Russian version of Scientific American magazine, which you can download here:

In the past 75 years, the Kurchatov Institute has performed many major roles in the Soviet / Russian nuclear industry and, with a national security focus, continues to be a driving force in that industry sector.

Now, lets take a look at a few of the pioneering nuclear projects led or supported by Kurchatov Institute:

  • F-1 (Physics-1) reactor
  • Plutonium production reactors
  • Obninsk nuclear power plant AM-1
  • T-1 Tokamak

F-1 (Physics-1) reactor

The F-1 reactor designed by the Kurchatov Institute was a graphite-moderated, air-cooled, natural uranium fueled reactor with a spherical core about 19 feet (5.8 meters) in diameter. F-1 was the first reactor to be built and operated outside of the US.  It was a bit more compact than the first US reactor, the Chicago Pile, CP-1, which had an ellipsoidal core with a maximum diameter of about 24.2 feet (7.4 meters) and a height of 19 feet (5.8 meters).

The F-1 achieved initial criticality on 25 December 1946 and initially was operated at a power level of 10 watts.  Later, F-1 was able to operate at a maximum power level of 24 kW to support a wide range of research activities. In a 2006 report on the reactor’s 60thanniversary by RT News (www.rt.com), Oleg Vorontsov, Deputy Chief of the Nuclear Security Department reported, “Layers of lead as they are heated by uranium literally make F1 a self-controlling nuclear reactor. And the process inside is called – the safe-developing chain reaction of uranium depletion. If the temperature rises to 70 degrees Celsius (158° Fahrenheit), it slows down by its own! So it simply won’t let itself get out of control.” 

F-1 was never refueled prior to its permanent shutdown in November 2016, after 70 years of operation.

Plutonium production reactors

The first generation of Soviet plutonium production reactors were graphite-moderated, natural uranium fueled reactors designed under the leadership of N.A. Dollezhal while he was at the Institute of Chemical Machinery in Moscow.  The Kurchatov Institute had a support role in the development of these reactors.The five early production reactors at Chelyabinsk-65 (later known as the Mayak Production Association) operated with a once-through primary cooling water system that discharged into open water ponds.

Four of the five later graphite-moderated production reactors at Tomsk had closed primary cooling systems that enabled them to also generate electric power and provide district heating (hot water) for the surrounding region.  You’ll find a good synopsis of the Soviet plutonium production reactors in the 2011 paper by Anatoli Diakov, “The History of Plutonium Production in Russia,” here:  

http://scienceandglobalsecurity.org/archive/sgs19diakov.pdf

Additional details on the design of the production reactors is contained in the 1994 Pacific Northwest Laboratory report PNL-9982, “Summary of Near-term Options for Russian Plutonium Production Reactors,” by Newman, Gesh, Love and Harms.  This report is available on the OSTI website here:

Obninsk was the site of the world’s first nuclear power plant (NPP).  This NPP had a single graphite-moderated, water-cooled reactor fueled with low-enriched uranium fuel. The reactor had a maximum power rating of 30 MWt.  AM-1 was designed by N.A. Dollezhal and the Research and Development Institute of Power Engineering (RDIPE / NIKIET) in Moscow, as an evolution of an earlier Dollezhal design of a small graphite-moderated reactor for ship propulsion.  The Kurchatov Institute had a support role in the development of AM-1.

The basic AM-1 reactor layout is shown in the following diagram.

The closed-loop primary cooling system delivered heat via steam generators to the secondary-side steam system, which drove a steam turbine generator that delivered 5 MWe (net) to the external power grid.   Following is a basic process flow diagram for the reactor cooling loops.

Construction on AM-1 broke ground on 31 December 1950 at the Physics and Power Engineering Institute (PEI) in Obninsk, about 110 km southwest of Moscow.  Other early milestone dates were:

  • Initial criticality:  5 May 1954
  • Commissioning and first grid connection:  26 June 1954
  • Commercial operation:  30 November 1954

In addition to its power generation role, AM-1 had 17 test loops installed in the reactor to support a variety of experimental studies. After 48 years of operation, AM-1 was permanently shutdown on 28 April 2002.

You can read more details on AM-1 in the following two articles: “Obninsk: Number One,” by Lev Kotchetkov on the Nuclear Engineering International website here:

 http://ansnuclearcafe.org/2015/06/24/anniversary-at-obninsk-the-first-commercial-nuclear-power-plant/#sthash.4wTrQueH.vhtfLcPK.dpbs

The AM-1 nuclear power plant design was developed further by NIKIET into the much larger scale RBMK (Reaktor Bolshoy Moshchnosti Kanalnyy, “High Power Channel-type Reactor”) NPPs.  The four reactors at the Chernobyl NPP were RBMK-1000 reactors.

The T-1 Tokamak

Research on plasma confinement is a toroidal magnetic field began in Russia in 1951, leading to the construction of the first experimental toroidal magnetic confinement system, known as a tokamak, at Kurchatov Institute. T-1 began operation in 1958.

Early operation of T-1 and successive models revealed many problems that limited the plasma confinement capabilities of tokamaks.  Solving these problems led to a better understanding of plasma physics and significant improvements in the design of tokamak machines.  You’ll find a historical overview of early Soviet / Russian work on Tokamaks in a 2010 IAEA paper by V. P. Smirnov, ”Tokamak Foundation in USSR/Russia 1950–1990,” which you can read here:

 https://fire.pppl.gov/nf_50th_5_Smirnov.pdf

The basic tokamak design for magnetic plasma confinement has been widely implemented in many international fusion research machines, winning out over other magnetic confinement concepts, including the Stellarator machine championed in the US by Dr. Lyman Spitzer (see my 30 August 2017 post on Stellarators).  Major international tokamak projects include the Joint European Torus (JET) at the Culham Center for Fusion Energy in Oxfordshire, UK, the Tokamak Fusion Test Reactor (TFTR) at Princeton Plasma Physics Laboratory in the US, the JT-60 at the Japan Atomic Energy Agency’s Naka Fusion Institute, and most recently the International Thermonuclear Experimental Reactor (ITER) being built now at the Saclay Nuclear Center in southern France.


Lots of Land Speed Record (LSR) Action in 2018

The first land speed record (LSR) at greater than 400 mph (643.7 kph) was set on 17 July 1964 by UK driver Donald Campbell in the wheel-driven, gas turbine-powered streamliner named Bluebird CN7. Regarding his new official land speed record of 403.10 mph (648.73 kph) in the measured mile, a disappointed Campbell is reported to have said, “We’ve made it – we got the bastard at last.”  Campbell thought the Bluebird CN7 was capable of much higher speeds, but did not mount another LSR challenger with that car.

This year, 54 years after Campbell’s record run, Team Vesco’s Turbinator II became the first wheel-driven vehicle to exceed 500 mph (804.7 kph).  In addition, there are several LSR contenders in diverse vehicle designs that regularly are making runs in the 400 – 500 mph range.  Donald Campbell might be impressed with the current state of the “sport.”  Let’s take a look at what’s happened in 2018.

1. Governing land speed records

The FIA (Fédération Internationale de L’Automobile) establishes the process for making world land speed record (LSR) attempts and certifying the resulting speeds.  FIA record attempts are standardized over a fixed length course (mile and kilometer) and averaged over two runs in opposite directions that must be completed within one hour.  The FIA’s home page for land speed records is at the following link:

https://www.fia.com/fia-world-land-speed-records

You’ll find the FIA’s technical regulations governing LSR attempts in Appendix D at the following link:

https://www.fia.com/appendix-d-regulations-land-speed-record-attempts-2018

The FIA defines four basic categories of LSR vehicles:

  • Category A LSR vehicles are purpose-built, wheel-driven automobiles that may be powered by any of a variety of engines, including Otto cycle (4-cycle), Diesel cycle (2-cycle), rotary, electrical, gas turbine, or steam, or any hybrid combination of these engines. 
  • Category B LSR vehicles are derived from series production automobiles, with the same basic engine options as Category A (as long as you can stuff it into a series production automobile). 
  • Category C applies to “special automobiles,” including LSR vehicles that are not wheel-driven, but instead are powered by the thrust of jet and/or rocket engines.
  • Category D LSR vehicles are drag racing automobiles.

Within Categories A and B, the FIA defines Groups based on fuel type and Classes based on engine displacement and vehicle weight.  In Category C, Groups may be defined based on engine type.

World motorcycle LSR records are managed separately by the FIM (Fédération Internationale de Motocyclisme).

In contrast to FIA LSR rules, US National land speed records are the average of two runs going in the same direction over a two-day period.  The rationale is that national events such as Bonneville Speed Week involve too many vehicles to swap directions on the course in less than 60 minutes.  The basic processes defined by the Southern California Timing Association (SCTA) and used during Speed Week are as follows:

For each run on the Bonneville five-mile long course, five different speeds are determined:

  • The first speed reported is referred to as the “quarter” and is the average speed over a 1,320-foot (quarter mile) timing trap that starts at the 2-mile marker. 
  • Next, times are recorded and average speeds are determined over three flying mile intervals: from mile 2 to mile 3, from mile 3 to mile 4 (the “middle mile”), and from mile 4 to mile 5. Official time slips refer to these as Mile 3, Mile 4, and Mile 5.
  • The final timing number is called “exit speed”, or terminal speed, which is an average speed measured over a 132-foot trap at the end of Mile 5.

When a car makes a first run at a speed greater than an existing record, it goes into “impound,” where the following process applies:

  • After being impounded, the team has four hours to work on the car. 
  • The team must be back at the track by 6 AM the next day, when it has another hour of prepare the car for the second run (i.e., add fuel, ice coolant, etc.). 
  • The car must be at the start line by 7 AM, ready to make its second run. 

If the average between the two runs is greater than the existing record, a new National record is awarded.

The SCTA defines several vehicle categories, with their Category A (special construction vehicles) being comparable to FIA Category A. 

2. Category C LSR contenders in 2018

Category C LSR contenders, with jet or rocket propulsion, have been the fastest LSR vehicles in the world since Craig Breedlove set the absolute land speed record at 407.447 mph (655.722 kph) in the measured mile at Bonneville on 5 August 1963 in the turbojet-powered, three-wheeled Spirit of America.  The FIA considered this to be an unofficial record because Spirit of America only had three wheels.  This record later was ratified by the FIM. Since 1963, six other Category C LSR vehicles have held the absolute land speed record:  Wingfoot Express, Green Monster, Spirit of America Sonic 1, Blue Flame, Thrust2 and ThrustSSC (supersonic car).

The current FIA absolute land speed records are: 

  • 763.035 mph (1,227.986 kph) for the measured mile, and 
  • 760.343 mph (1,223.657 kph) for the measured kilometer

These records were set on 15 October 1997 by the UK LSR vehicle Thrust SSC, which completed the required two runs in opposite directions within one hour on a track in the Black Rock Desert in Nevada.  Thrust SSC was driven by Andy Green when it became the first supersonic LSR vehicle, achieving an average speed through the measured gates of Mach 1.016.

In 2018, the two primary Category C LSR contenders were the UK Bloodhound SSC, which is under development and successfully completed low speed trials (> 200 mph, 322 kph), and the US North American Eagle, which has been running for many years and has reached a maximum speed of > 500 mph (805 kph).  Following is a brief review of these Category C LSR programs.

Bloodhound SSC – Did it die in 2018, or is there still hope? 

In posts in March 2015, September 2015 and January 2017, I reported on the ambitious UK project to create a 1,000 mph land speed record car known as the Bloodhound SSC. 

In 2006, Lord Drayson, the UK Minister of Science, proposed developing a new UK LSR vehicle to LSR holders Richard Noble (Thrust 2) and Andy Green (Thrust SSC).  This led to the formation of the Bloodhound SSC project, which was announced on 23 October 2008, along with an associated education component designed to inspire future generations to take up careers in science, technology, engineering and mathematics (STEM). The Bloodhound SSC project website is here:

http://www.bloodhoundssc.com/project

Original plans were for the Bloodhound SSC to make its LSR runs on the Hakskeen Pan in South Africa (see my March 2015 post), with initial trial runs starting in 2016.  As development of Bloodhound SSC continued, the dates for the initial LSR runs slipped gradually to 2017, 2018 and most recently to the end of 2019.

In 2017, Bloodhound SSC conducted five weeks of testing, including its first successful public “shakedown” run on 26 October 2017, on the 9,000 foot (1.67 mile, 2.7 km) runway at the Cornwall Airport in Newquay, UK.  Powered by its Rolls-Royce EJ200 jet engine and driven by Andy Green, Bloodhound SSC reached a modest top speed of 210 mph (378 kph) on this short runway.

You’ll find a YouTube video of the Newquay trial runs here:

The trials at Newquay demonstrated the satisfactory performance of vehicle systems and provided confidence for further development and testing. In 2018, Bloodhound SSC remained in the UK, but no further trial runs were made.

In 15 October 2018, Bloodhound Programme Ltd., the UK company behind the Bloodhound SSC, entered into “administration,” which is comparable to a Chapter 11 filing in the US and is intended to give a company in financial difficulties protection from creditors for a limited period while it attempts to reorganize and seek new financing. Bloodhound Programme Ltd. was seeking about $33 million (about £25 million) to fund the program through the actual land speed record attempts in South Africa in 2020 – 2021.

Source: http://www.bloodhoundssc.com/news/

On 7 December 2018, BBC News reported that the attempts to reorganize had failed.  Joint administrator Andrew Sheridan reported, “Despite overwhelming public support, and engagement with a wide range of potential and credible investors, it has not been possible to secure a purchaser for the business and assets.” You can read the BBC report here:

https://www.bbc.com/news/uk-england-bristol-46480342

Plans are being implemented to return or sell assets.  Driver Andy Green said the Bloodhound SSC vehicle was now available for sale at a price of about £250,000 ($318,275).

Let’s hope that the Bloodhound SSC project can find a last minute investor and a route to recovery.

North American Eagle – Continuing to make progress in 2018

Ed Shadle and Keith Zanghi started the North American Eagle LSR project 20 years ago, in 1998.  Their idea was to take a surplus Lockheed F-104 jet fighter fuselage with a General Electric J-79 jet engine and afterburner and create a viable absolute LSR challenger.  The result of their efforts, with assistance from a team of volunteers and support from many sponsors, is the North American Eagle LSR vehicle shown below.

You can view a YouTube video on the North American Eagle LSR program here:

Here’s a shorter video of the September 2016 speed run in the Alvord Desert in Oregon. During this run, driver Jessi Combs achieved a maximum speed of 477.59 mph (768.60 kph):

The North American Eagle team website reports:  “To date, we have made over 57 test runs, already attaining a top speed of 515 mph. This is only the beginning though.  In September 2018, with Jessi Combs at the helm, she made a 483.227 mph (run).  In 2019 she will attempt (to exceed) the 512 mph Fastest Woman record, as well as the single engine speed record. Both of these are major milestones on the road to 800 mph.”

Founder Ed Shadle died on 7 September 2018.  Jessi Combs is now the primary driver and the team is expecting to continue its LSR program in 2019.

3. Category A LSR contenders in 2018

At the beginning of 2018, the FIA land speed record for wheel-driven, piston-powered vehicles was held by Speed Demon, which set the record on 17 September 2012:

  • 439.024 mph (706.540 kph) for the measured mile, and
  • 439.562 mph (707.408) kph for the measured kilometer 

The FIA record for wheel-driven, turbine-powered vehicles was held by Turbinator, which set the record on 18 October 2001:

  • 458.444 mph (737.794 kph) for the measured mile, and
  • 458.196 mph (737.395 kph) for the measured kilometer 

2018 was an exciting year in Category A, with the two primary Category A LSR contenders, Challenger 2 and Turbinator II, raising their respective speed records for wheel-driven vehicles and Turbinator II making the first unofficial Category A one-way run at > 500 mph (805 kph). Five different LSR vehicles made runs at > 400 mph (644 kph) during the SCTA Bonneville Speed Week, which was held from 11 – 17 August 2018: 

  • Challenger 2 
  • Turbinator II 
  • Speed Demon 
  • Flashpoint 
  • Carbiliner 

At the rain foreshortened Bonneville World Finals held on 2 October 2018, the following three LSR vehicles made runs at > 400 mph (644 kph):

  • Turbinator II
  • Speed Demon
  • Eddie’s Chop Shop streamliner

Following is a brief review of these Category A LSR programs.

You’ll find the complete results from Speed Week 2018, World Finals 2018 and other SCTA events on their website:

Challenger 2 – Raised the wheel-driven, piston engine LSR in 2018

On 9 September 1960, Mickey Thompson, driving the four-engine, wheel-driven Challenger 1 streamliner, achieved a one-way speed of 406.60 mph (654.36 kph) in the flying mile on the Bonneville Salt Flats. Unfortunately, Challenger 1 was was unable to make the second run required by the FIA for an official land speed record.  Thus, the existing absolute and Category A LSRs set on 16 September 1947 by John Cobb driving the Railton Mobile Express continued to stand at 394.19 mph (634.39 kph) for the measured mile and 394.196 mph (643.196 kph) for the measured kilometer.

Cobb’s absolute LSR was eclipsed on 5 August 1963 by Craig Breedlove, driving the turbojet-powered (Category C, not wheel-driven) Spirit of America to a speed of 407.447 mph (655.722 kph) in the measured mile on the Bonneville Salt Flats.

The following year, Cobb’s wheel-driven LSR was further eroded on 17 July 1964 when Donald Campbell set a Category A record of 403.10 mph (648.73 km/h) in the measured mile in the wheel-driven, Proteus gas turbine-powered Bluebird CN7 on the dry salt bed at Lake Eyre, Australia.

Cobb’s wheel-driven, piston engine LSR record and Campbell’s wheel-driven LSR both fell on 12 November 1965 when Bob Summers drove the four-engine Goldenrod LSR car to 409.277 mph (658.526 kph) in the measured mile on the Bonneville Salt Flats.  By then, several turbojet-powered Category C LSR vehicles and had raised the absolute LSR to more than 555 mph (893 kph).

In an effort to regain the Category A LSR crown, Mickey Thompson built the greatly improved Challenger 2 for a planned LSR challenge in 1968. The unblown (not supercharged), two-engine Challenger 2 ran at the Bonneville Salt Flats in 1968 with trial speeds approaching 400 mph (644 kph), but rain prevented an LSR run that year.  Following the loss of key LSR sponsors in 1969, Mickey Thompson mothballed the Challenger 2 for almost two decades.

Mickey Thompson and son Danny removed Challenger 2 from storage in January 1988 and developed plans for a 1989 LSR challenge. These plans were cancelled following the tragic murder of Mickey Thompson and his wife in March 1988. Once again, Challenger 2 was placed in long-term storage. In 2010, Danny Thompson began efforts to prepare Challenger 2 for an LSR run intended to “vindicate his father’s faith in the streamliner.”  The modernized Challenger 2 retained the original chassis and hand-formed aluminum skin, resulting in an almost unchanged external appearance.  The original engines and drive trains were removed and replaced by more powerful dry block, nitromethane-fueled, unblown Hemi V8 engines in an all-wheel drive configuration. Other modifications were made to comply with current FIA and SCTA regulations for LSR attempts. You’ll find details on the updated Challenger 2 on the Thompson LSR website here:

http://thompsonlsr.com/about/

Challenger 2 test runs started in June 2014 and speed runs on Bonneville’s full-length course began in September 2014.  

On 12 August 2018, during Bonneville Speed Week and 50 years after its original runs at Bonneville, Challenger 2 driven by Danny Thompson set a new class record of 448.757 mph (772.204 kph) for the measured mile, breaking the record held by Speed Demon since September 2012.  This record currently stands as the fastest overall wheel-driven, piston-powered land speed record.  You can view a YouTube video on the Challenger racing team and the 2018 LSR run here:

The Challenger 2 is now retired. Thank you Danny Thompson for resurrecting this amazing car and mounting a successful LSR challenge. Your Dad, Mickey Thompson, would be very proud of you and your team.

Turbinator II – Raised the wheel-driven vehicle LSR record in 2018

Team Vesco has been a long-time contender in land speed record racing.  You’ll find a history of and their many projects and LSR challenges on the team website here:

http://www.teamvesco.com/home.html

Team Vesco introduced the original Turbinator to the public in 1996 with the goals of setting a new wheel-driven LSR and becoming the first wheel-driven vehicle to exceed 500 mph.  Turbinator was powered by a single, stock 3,750 hp Lycoming T55 gas turbine engine (a former turboshaft helicopter engine) delivering power to a four-wheel drive system.  On 18 October 2001, the Turbinator, driven by Don Vesco, eclipsed Donald Campbell’s 37-year old land speed record, raising the FIA Category A LSR to 458.440 mph (737.788 kph). 

A 2011 paper in the University of Leicester (UK) Journal of Physics Special Topics, by Back, Brown, Hall and Turner, estimated the top speeds of the Turbinator to be 486 mph (782 kph) and its follow-on, the Turbinator II with a 4,400 hp engine, to be 509 mph (819 kph).  You can read this paper here:

https://journals.le.ac.uk/ojs1/index.php/pst/article/view/1995/1897

Turbinator II is an update of the original Turbinator, using an uprated Lycoming gas turbine delivering somewhere between 4,300 – 5,000 hp power to all four wheels. You can see what a high speed run in Turbinator II looks like in the following video made on 13 August 2018 when driver Dave Spangler raised the fastest mile speed to 463.038 mph (745.187 kph) during Bonneville Speed Week.

Just six weeks after Danny Thompson raised the LSR for wheel-driven, piston-engine vehicles to 448.757 mph (772.204 kph) with Challenger 2, Team Vesco raised the wheel-driven vehicle National class record to 482.646 mph (776.743 kph) on 15 September 2018 with Dave Spangler driving Turbinator II at the Bonneville World of Speed time trials hosted by the Utah Salt Flats Racing Association (USFRA).

At the Bonneville World Finals on 2 October 2018, Turbinator II made a one-way run through the measured mile of 493.996 mph (795.009 kph), with an exit speed of 503.332 mph (810.034 kph). Turbinator II became the world’s first wheel-driven vehicle to exceed 500 mph and 800 kph.  Weather precluded making the second run needed for an official record. You can view this speed run here:

With continuing improvements being made to the vehicle, Turbinator II appears to be a good candidate for being the first LSR vehicle to set an FIA land speed record at > 500 mph.

Speed Demon

On 17 September 2012, Speed Demon, driven by George Poteet at Bonneville, established an FIA Category A land speed record of 439.024 mph (706.540 kph) for the measured mile and 439.562 mph (707.408 kph) for the measured kilometer.  For this record run, Speed Demon was powered by a turbocharged, 2,200 hp, 368 cubic inch small block Chevy engine driving the rear wheels. This record stood until 12 August 2018 when it was eclipsed by Danny Thompson in the Challenger 2.

Source:  http://landspeedevents.com/blog/poteet-and-main/

The original Speed Demon was destroyed on 12 September 2014 after a crash at 375 mph (606 kph) during a speed run at Bonneville, possibly due to a temporary loss of traction on the salt track.  You can read a synopsis of George Poteet’s recollection of this crash here:

https://www.good-guys.com/hotnews/george-poteet-recalls-375mph-bonneville-crash/

In an all-new Speed Demon II, George Poteet returned to land speed racing in 2016.  The new Speed Demon is powered by a single, twin-turbocharged, small-block V8 engine delivering over 2,600 hp to the rear wheels.  You’ll find details on Speed Demon’s V8 piston engine here:

The Speed Demon II. Source: Speed Demon Racing

In its current incarnation, Speed Demon is a strong LSR challenger that appears to have the potential to exceed 500 mph.

  • During Bonneville Speed Week in August 2018, Speed Demon made three runs at > 400 mph, with the fastest being 452.255 mph.
  • During the foreshortened Bonneville World Finals in October 2018, Speed Demon made one run at 431.435 mph.

Flashpoint Streamliner

Flashpoint streamliner made its debut on the Bonneville Salt Flats in 2013. It is powered by a 482 cubic inch, nitromethane burning blown Hemi V8. In its 2013 debut, the streamliner achieved a top speed of 395 mph (636 kph). The team has announced a goal of exceeding 500 mph (805 kph).

The Flashpoint team homepage is at the following Facebook site:

https://www.facebook.com/Flashpoint7800/

On 16 September 2018, during the USFRA World of Speed at Bonneville, the Flashpoint Streamliner achieved a speed of 436.308 mph (702.170 kph) on its first run of the five-mile long course, with an exit speed of 451.197 mph (726.131 kph). On the second run, a tire failed at 427 mph (687 kph), causing a spectacular rollover crash.  Fortunately (and incredibly), driver Robert Dalton was uninjured.

Hopefully, the Flashpoint team will rebuild and we’ll see the next iteration of the potent Flashpoint Streamliner back in action in the future.

Carbinite LSR streamliner (Carbiliner)

Source, both photos above:  Carbinite LSR

The Carbiliner was designed and built over a seven-year period and made its first appearance at the Bonneville Speed Week in 2016.  It is a radically designed Category A streamliner, similar in design to successful Category C jet- and rocket-powered LSR vehicles from the early 1970s.  The Carbininte LSR team notes:

“Past efforts and current mindset in building Streamliners has focused on keeping the car aerodynamically neutral (no lift or downforce). This necessitates the addition of significant amounts of ballast to obtain enough traction for acceleration, resulting in two problems:

  1. The racing surface at Bonneville is not as flat as it once was due to deterioration of the salt. This causes the car to skip across the salt at higher speeds, breaking traction.
  2. The increased weight of the cars leads to slower acceleration. Cars may run out of track prior to reaching maximum speed.

The Carbinite LSR Streamliner design has addressed these problems.”

On means is through the use of active aerodynamic control surfaces on the rear wings (NACA 66-018 profile) that support the rear wheels and house the drive shafts.  The control surfaces are designed to generate over 3,000 pounds (1,361 kg) of downforce with minimum drag.  At low speed, the aerodynamic control surfaces are “full-up” at the start of acceleration.  As speed increases, the flaps are lowered to maintain the same amount of downforce. The flaps, speed-based boost control and fuel injection are managed by a Holley engine control unit (ECU).

The Carbiliner is powered by a single, twin-turbocharged, 540 cubic inch Chevy V8 burning methanol (starting in 2017) and delivering 2,400 – 2,800 hp to the the unsprung (no suspension) rear wheels. You’ll find a good technical description of the vehicle here:

The team’s primary goal is “to break the 500 mph barrier at the next Bonneville Speed Week and become the fastest wheel driven car on the planet”.  In 2018, it was one of five LSR vehicles to exceed 400 mph during Speed Week, making runs of 406.750 mph (654.601 kph) and 413.542 mph (665.531 kph).  The team has work to do, but this radical LSR may have the potential to achieve their primary goal.

Like the Bloodhound SSC project, the Carbinite LSR team has established an education program “to excite the next generation of students about careers in STEM, and to inspire students to think big!  Our program is geared for high school physics and shop students, as well as college engineering students.”  You’ll find a good video describing the Carbiliner’s aerodynamics and the STEM education program here:

Eddie’s Chop Shop streamliner

Ed Umland, of Orangevale, CA, reportedly built his 29-foot blown gas, aluminum bodied streamliner in 18 months with the goal of being able to exceed 400 mph at Bonneville.  The streamliner is powered by a single, twin-turbo, 439 cubic inch V8 engine driving the rear wheels.

On 2 October 2018, during the foreshortened Bonneville World Finals, this streamliner achieved a speed of 403.996 mph (650.169 kph) in the measured mile, with an exit speed of 411.209 mph (661.777 kph).  Ed Umland has achieved his original goal, and his streamliner appears to have the potential to achieve higher speeds in the future.

4. In conclusion

The upper echelon of land speed racing is alive and well, in spite of the likely demise of the Category C Bloodhound SSC program.  There is great competition among the Category A wheel-driven LSR contenders in the 400 – 500 mph range, with records being raised in 2018 and the 500 mph and 800 kph “barriers” being broken for the first time. Next year should be pretty interesting, especially if the salt flats are in good condition.

I hope the Bloodhound SSC program will get a last-minute (last second) reprieve and, as in the 1975 movie Monty Python and the Holy Grail,  be able to say, “I’m not dead yet.” 

25 December 2018 Christmas Day Update:  Yes, Virginia, there is a Santa Claus.

On Monday 17th December, the Bloodhound Project announced that its business and assets were bought by Yorkshire-based entrepreneur Ian Warhurst, who stated: “I am delighted to have been able to safeguard the business and assets, preventing the project breakup. I know how important it is to inspire young people about science, technology, engineering and math, and I want to ensure BLOODHOUND can continue doing that into the future.”

Thank you Ian Warhurst for your Christmas gift to the Bloodhound Team and the land speed racing community.


60th Anniversary of the Atomium

The official Atomium’s website reports that 2018 marks the 60thanniversary of this iconic mid-century “atomic age” structure in Brussels.

“The Atomium was the main pavilion and icon of the World Fair of Brussels (1958), commonly called Expo 58.  It symbolized the democratic will to maintain peace among all the nations, faith in progress, both technical and scientific and, finally, an optimistic vision of the future of a modern, new, super-technological world for a better life for mankind.

The peaceful use of atomic energy for scientific purposes embodied these themes particularly well and, so, that is what determined the shape of the edifice.  At 102 meters high, with its nine interconnected spheres, it represents an elementary iron crystal enlarged 165 billion (thousand million) times. It was dreamed up by the engineer André Waterkeyn (1917-2005).  The spheres, though, were fitted out by the architects André and Jean Polak.

The Atomium was not intended to survive beyond the 1958 World Fair but its popularity and success soon made it a key landmark, first of Brussels then internationally.

Half a century later, the Atomium continues, for that matter, to embody those ideas of the future and universality.  And, among other things through its cultural programming, it carries on the debate begun in 1958:  What kind of future do we want for tomorrow?  What does happiness depend on?

Over and above the symbolic value linked to its history, the Atomium has become one of the icons of the city of Brussels: capital of Europe, with which it has a special relationship. Since its inspired restoration (2006), the landmark that many people call the most Belgian monument is also a museum with its permanent collections and temporary exhibitions.

The completely steel-clad Atomium is a kind of UFO in the cultural history of humanity, a mirror turned simultaneously towards the past and the future, comparing our utopias of yesterday with our dreams for tomorrow”

As originally built, the Atomium had a load-bearing steel structure enclosed in an aluminum skin.  After 40 years, the aluminum skin had lost its sheen and gaps had opened up in the joints between panels.  The two-year restoration, which was completed in February 2006, involved removing the aluminum skin and replacing it with a new polished stainless steel skin that maintained the original design while adding LED exterior lighting and other modern features for thermal, sound and fire insulation. You’ll find details on the renovation project in a 2007 Euro Inox report at the following link:

Two US Supercomputers are Ranked Fastest in the World

In previous posts on 24 May 2015 and 28 June 2016, I reported on the TOP500 rankings of the world’s supercomputers.

In June 2013, China’s Tianhe-2 supercomputer at the National Supercomputer Center in Guangzho topped this this worldwide ranking with an Rmax Linpack score of 33 petaflops/second and retained the first place position for two years. In June 2016, the new leader was another Chinese supercomputer, the Sunway TaihuLight at the National Supercomputer Center in Wuxi. TaihuLight delivered an Rmax Linpack score of 93 petaflops/second and remained at the top of the worldwide ranking for two years, until it was eclipsed in June 2018 by the US Summit supercomputer, then with an Rmax rating of 122.3 petaflops / second.

In the latest TOP500 ranking, the new leaders are two US supercomputers:  Summit (#1) and Sierra (#2).

The IBM Sierra also improved its past Linpack score to achieve an Rmax of 94.64 petaflops / second and move into second place, marginally ahead of China’s TaihuLight.  Sierra is located at the DOE Lawrence Livermore National Laboratory (LLNL) in California.

  • 1,572,480 cores
  • 438 megawatts peak power

The Summit and Sierra supercomputer cores are IBM POWER9 central processing units (CPUs) and NVIDIA V100 graphic processing units (GPUs).   NVIDIA claims that its GPUs are delivering 95% of Summit’s performance. Both supercomputers use a Linux operating system.

China’s Sunway TaihuLight was ranked 3rd, and Tianhe-2A was ranked 4th.  A total of five DOE supercomputers were in the top 10 positions.

20 February 2019 Update:  Los Alamos National Laboratory (LANL) plans new supercomputer

The TOP500 ranking places LANL’s Trinity supercomputer (a Cray XC40) as the #6 fastest supercomputer in the world, but its performance (Rmax of 20.16 petaflops / second) is far below that of the #1 Summit supercomputer at Oak Ridge national Laboratory and the #2 Sierra supercomputer at Lawrence Livermore National Laboratory.

Not to be outdone, LANL issued a request for proposal (RFP) in February 2019 for a new supercomputer, to be named Crossroads, to support the lab’s missions for the National Nuclear Security Administration (NNSA).  A LANL spokesperson reported that, “High performance computing across the NNSA complex is used to assure the safety, security and effectiveness of the U.S. nuclear deterrent; to analyze and predict the performance, safety, and reliability of nuclear weapons and certify their functionality.”  Responses to the RFP are due by 18 March 2019.  Crossroads is expected to go online in 2021.
