SIPRI Yearbook 2020

X. Global stocks and production of fissile materials, 2019

Chapter:: 10. World nuclear forces
Source:: SIPRI Yearbook 2020
Author(s):: Shannon N. Kile, Hans M. Kristensen

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 2019, 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 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 2019 and give data for 31 December 2018, and so are taken here to be applicable for the start of 2019.
