Global Stocks of Nuclear Explosive Material
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.
