SIPRI Yearbook 2023
X. Global stocks and production of fissile materials, 2022
Materials that can sustain an explosive fission chain reaction are essential for all types of nuclear explosive, from first-generation fission weapons to advanced thermonuclear weapons. The most common of these fissile materials are highly enriched uranium (HEU) and plutonium. This section gives details of military and civilian stocks, as of the beginning of 2022, of HEU (table 7.11) and separated plutonium (table 7.12)—including in weapons—and details of the capacity to produce these materials (tables 7.13 and 7.14). The information in the tables is based on estimates prepared for the International Panel on Fissile Materials (IPFM). The most recent annual declarations on civilian plutonium and HEU stocks to the International Atomic Energy Agency (IAEA) give data for 31 December 2021 (INFCIRC/549).
