Preparation of U-Pu alloy for metallic fuel fabrication, 2; Reductive extraction of U and Pu from molten salt using Cd-Li alloys

Kato, Tetsuya*; Nakamura, Kinya*; Iwai, Takashi; Arai, Yasuo

In the pyrometallugical reprocessing of spent metallic fuel, U and Pu are recovered into liquid Cd through molten salt and subsequentry purified by distillation of Cd. In this study, U and Pu in molten salt were extracted into liquid Cd that had contained Li metal as reductant. The product of Cd-U-Pu alloys was heated to distill Cd and then, the obtained U-Pu alloys were supplyed for fabrication test of U-Pu-Zr metallic fuels.
