“World’s Fissile Material Data” 2024 [All Lists]
As was the case last year, the total amount of highly enriched uranium (HEU) declined but the total amount of separated plutonium increased, and the increasing tendency continues.
The total inventory of HEU was 1,255 tons, equivalent to 19,610 warheads (a decrease of 5 tons or about 70 warheads from last year). However, the overall rising trend in separated plutonium continues, with an increase of 7 tons in plutonium for civilian use, bringing the total inventory to 560 tons, equivalent to 93,270 warheads (an increase of 8 tons or about 1,270 warheads from last year). As a result, the total inventory amount increased to equivalent to 112,880 warheads, an increase of around 1,200 warheads from last year (111,680 warheads).
