Novouralsk, Zelenogorsk, Angarsk and Seversk
Capacity
29,133tSWU/yr
Novouralsk, Zelenogorsk, Angarsk and Seversk is a enrichment facility operated by TVEL Fuel Company in Russia. It has a capacity of 29,133 tSWU/yr as of 2025, about 43% of world enrichment capacity.
Four plants holding roughly 43% of world enrichment capacity — more than the rest of the world combined outside China. This single number is the reason enrichment is treated as a strategic dependency: until the 2024 US import ban, Russia supplied around a fifth of US reactor fuel enrichment, and it remains the only established commercial source of HALEU.
