Russia: Fissile Material Table


The following table provides information on highly enriched uranium and separated plutonium stockpiles at sites in Russia. Because of uncertainties in Russian fissile material inventories, these tables are not exhaustive. For HEU, the mass of U-235 is listed along with the enrichment. When only an aggregate amount of HEU with various enrichments is known, the total weight of the HEU inventory is listed. The table includes stocks of fresh fuel or fuel currently loaded in reactors. Spent fuel is not included.
