Materials that can sustain an explosive fission chain reaction are essential for all types of nuclear explosives, 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 2018 of HEU (table 6.11) and separated plutonium (table 6.12), including in weapons, and details of the current capacity to produce these materials (tables 6.13 and 6.14, respectively). The information in the tables is based on estimates prepared for the International Panel on Fissile Materials (IPFM). The most recent annual declarations (INFCIRC/549 declarations) on civilian plutonium and HEU stocks to the International Atomic Energy Agency (IAEA) were released in late 2018 and give data for the end of 2017. As of January 2019, the civilian plutonium declarations by China, France, the United Kingdom and the United States—states that have submitted such annual declarations since 1997—were not available.
