International Panel on Fissile Materials (IPFM)

The IPFM was founded in January 2006 and is an independent group of arms-control and nonproliferation experts from both nuclear weapon and non-nuclear weapon states. It is based at the Program on Science and Global Security. The mission of the IPFM is to analyze the technical basis for practical and achievable policy initiatives to end production and use of highly enriched uranium and plutonium and to secure, consolidate, and reduce stockpiles. These fissile materials are the key ingredients in nuclear weapons, and their control is critical to nuclear weapons disarmament, to halting the proliferation of nuclear weapons, and to ensuring that terrorists do not acquire nuclear weapons.

As of the beginning of 2019, the global stockpile of highly enriched uranium (HEU) was estimated to be about 1335 metric tons. The global stockpile of separated plutonium was about 530 tons, of which about 310 tons was civilian plutonium.
