Plutonium & Highly Enriched Uranium 2015

Lindner Commons, 6th floor, 1957 E Street, NW Washington, DC 20052

The Institute for Science and International Security periodically develops estimates of national inventories of plutonium, highly enriched uranium (HEU), and other nuclear explosive materials. These estimates cover inventories used to make nuclear weapons and those part of civil nuclear programs. The nuclear explosive materials are categorized by country, quantity, origin, and use (military or civil). Understanding the size, status, and production of these materials is essential to preserving international security and reducing the risk of nuclear war, proliferation, and terrorism.

The 2015 collection of studies, funded largely by a generous grant from the Nuclear Threat Initiative, contains comprehensive national estimates of plutonium and highly enriched uranium (HEU) stocks as of the end of 2014. 

At this briefing, David Albright and Serena Kelleher-Vergantini will present the 2015 HEU and plutonium estimates, findings, and recommendations for the upcoming 2016 Nuclear Security Summit.

Please RSVP to by Wednesday, March 23, 2016. A light lunch will be provided.
