Status Report on Global Nuclear Weapon and Fissile Material Stockpiles

Peter Lobner

The International Panel on Fissile Materials (IPFM) was founded in January 2006 as an independent group of arms-control and nonproliferation experts from both nuclear weapon and non-nuclear weapon states. The mission of the IPFM is to analyze the technical basis for practical and achievable policy initiatives to secure, consolidate, and reduce stockpiles of highly enriched uranium (HEU) and plutonium. The home page for IPFM is at the following link:

On the IPFM home page, you will find the following summary information:

 As of January 2013, the global stockpile of highly enriched uranium (HEU) is estimated to be about 1390 tonnes. The global stockpile of separated plutonium is about 490 tonnes, of which about 260 tonnes is the material in civilian custody.

Numbers for weapon plutonium for the United States and United Kingdom are based on official data. Most numbers for civilian plutonium are based on declarations submitted to IAEA and reflect the status as of December 31, 2011. Other numbers are non-governmental estimates, often with large uncertainties. HEU amounts are 90% enriched HEU equivalent (with the exception of the number for non-nuclear weapon states). The totals are rounded. See individual country entries for details.

In the above table, a “tonne” is a metric ton, or 2,204.62 pounds. One tonne = 1.10231 (short) tons.

IPFM provides regular assessments of the global nuclear weapon and fissile material stockpiles. Their most recent report, Global Fissile Material Report 2015, was presented at the Non-Proliferation Treaty (NPT) Review Conference at the United Nations on 8 May 2015.
