Nuclear fuel reprocessing |
| abstract |
This application relates to nuclear fuel reprocessing and is particularly concerned with the separation of uranium from plutonium and neptunium. The method provides spent fuel reprocessing in which an organic phase containing U, Pu and Np is contacted with a reductant to reduce Pu to Pu(III) and Np(VI) to Np(V). The Pu(III) and Np(V) are extracted into an aqueous phase with Np(VI) remaining in a solvent phase. The solvent phase is contacted with a hydrophilic complexant which form a complex with Np(IV). The complex is then extracted into a further aqueous phase. The U remains in the solvent phase from which it can be isolated. There is also described a Purex reprocessing plant which comprises apparatus for separation of uranium from plutonium and neptunium. |
