Nuclear Fuel Cycle – Front-end Back to menu


Conversion plants are operating commercially in the US, Canada, France, Russia and China. The main new plant is Areva’s Comurhex II, operating between two sites in France, at Malvési and Tricastin, and expected to reach its nameplate capacity in 2022. China’s capacity is expected to grow considerably through to 2025 and beyond, as the country plans to keep pace with domestic requirements and become a strong player in the global nuclear fuel market.

In 2017, world nameplate primary conversion capacity was estimated at around 57 500 tU, with the actual conversion production assumed at 45 740 tU. Part of the supply continued to be provided by secondary conversion sources. Secondary supply of equivalent conversion services includes UF6 material from commercial and government inventories, enricher underfeeding and depleted uranium tails recovery. Uranium and plutonium recycling add to this. Supply provided by primary and secondary conversion sources was able to meet the global demand for conversion services.
