Nuclear fuel fabrication

BOTTLENECK

Nuclear fuel assemblies are qualified per reactor design and not fungible across types, so each fleet depends on the one or two makers licensed for it.

Manufacture of fuel pellets, rods, and assemblies qualified for specific reactor designs. Not fungible across reactor types. Westinghouse, Framatome, and GE-Hitachi dominate LWR fuel; TRISO and HALEU metallic fuel capacity for advanced reactors remains commercially thin.

What the evidence shows

Fuel fabrication capacity for all types of LWR fuel worldwide considerably exceeds demand.

Westinghouse has three world-class fuel fabrication facilities in the United States, Sweden and the U.K.
