Fostering initiatives to reduce stocks and end the production and use of highly enriched uranium and plutonium... As of the beginning of 2022, the global stockpile of unirradiated highly enriched uranium (HEU) was estimated to be about 1250 metric tons. Most of this material - about 1,100 metric tons - is in weapons or available for use in weapon programs. The global stockpile of separated plutonium was about 550 tons. Of this material, 410 metric tons were produced outside of weapon programs, covered by obligations not to use it in weapons, or not directly suitable for weapons. This leaves about 140 metric tons of plutonium in weapons or available for weapons.
