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 2021, of HEU (table 10.11) and separated plutonium (table 10.12), including in weapons, and details of the current capacity to produce these materials (tables 10.13 and 10.14, respectively). The timeliness of the information here is constrained by the most recent annual declarations on civilian plutonium and HEU stocks to the International Atomic Energy Agency (IAEA; INFCIRC/549), which give data for 31 December 2020. The information in the tables is based on estimates prepared for the International Panel on Fissile Materials (IPFM).1
