If any. NuScale was going to use this stuff. But that project was cancelled a few weeks ago. Costs too much. There are advanced reactors being talked about. Does anyone know of any that actually need this fuel right now? Maybe outside the US there are some.
(NRC: "Natural uranium is made of about 0.7 % U-235 and traditional reactor fuel is enriched to between 3% and 5% U-235." High-assay, low-enriched uranium is, per the NRC, 5% - 20% u-235. Weapons grade is around 90%.)
