2019 civilian plutonium and HEU declarations submitted to the IAEA

This post contains a summary of INFCIRC/549 reports by the countries that submit annual civilian plutonium declarations that reflect the status of civilian plutonium stocks as of 31 December 2019.

  1. Japan (INFCIRC/549/Add.1-23) reported owning the total of 45.5 tons of plutonium, 8.9 tons of which is in Japan (the numbers in 2018 were 45.7 tons and 9.0 tons respectively). According to the Status Report on Plutonium Management in Japan - 2019 released in August 2020, out of the 36.6 tons of plutonium abroad, 21.180 tons are in the United Kingdom and 15.435 tons are in France.

  2. Germany (INFCIRC/549/Add.2-23) reported having no separated plutonium in the country for the second year in a row. Germany does not report separated plutonium outside of the country. It is believed to be less than 1 ton.

  3. Belgium (INFCIRC/549/Add.3-19) declared no separated plutonium in storage or at reprocessing plants and "not zero, but less than 50 kg" of separated plutonium in other categories. It reported that it had no foreign plutonium as of 31 December 2018.

  4. Switzerland (INFCIRC/549/Add.4-24) reported having less than 2 kg of plutonium in the country (in the "located elsewhere" category). The number has not changed since 2016 (it was "less than 50 kg" in 2015).

  5. France (INFCIRC/549/Add.5-24) reported having 90.2 tons of separated unirradiated plutonium in its custody. Of this amount, 15.5 tons belongs to foreign countries. It appears that all that plutonium - 15,435 kg - belongs to Japan. The amount of plutonium owned by France is 74.7 tons, an increase of 7 tonnes from previous year (67.7 tons).

  6. The United States has not submitted its 2019 report as of 5 September 2020.

  7. China has not has not submitted its 2017-2019 reports as of 5 September 2020. The last INFCIRC/549 report submitted to the IAEA showed 40.9 kg of separated plutonium as of 31 December 2016.

  8. The United Kingdom has not submitted its 2019 report as of 5 September 2020.

  9. Russia has not submitted its 2019 report as of 5 September 2020.

In addition to reporting plutonium stocks, some countries also submit data on their civilian HEU:

Germany reported 0.35 tonnes of HEU in research reactor fuel (an increase from 0.32 tonnes in 2018), 0.94 tonnes of HEU in irradiated research reactor fuel, and 0.01 tonnes in the category "HEU held elsewhere."

France declared 5373 kg of HEU (5144 kg in 2017), of which 3836 kg (3654 kg) is unirradiated material - 930 kg (996 kg) of HEU at fuel fabrication or reprocessing plants, 51 kg (101 kg) at civil reactor sites, 2855 kg (2517 kg) at various research facilities. Also declared are 1537 kg (1530 kg) of irradiated HEU - 99 kg (91 kg) at civil reactor sites and 1438 kg (1439 kg) in other locations.

The United Kingdom has not submitted its 2019 report as of 5 September 2020.
