<p><P>PROBLEM TO BE SOLVED: To provide extraction equipment and a spent nuclear fuel reprocessing facility capable of inhibiting nuclear proliferation by extracting uranium and plutonium without isolating plutonium when a plurality of types of spent nuclear fuels are reprocessed in a single reprocessing facility. <P>SOLUTION: Extraction equipment includes: a plurality of extractor 40 which can be separated into an organic phase and an aqueous phase; an extraction solvent input port 52 for flowing an extraction solvent T into the extractor; a loaded solvent input port 51 for flowing a U/Pu-loaded solvent T1 into the extractor; and a back extraction liquid inflow port 53 for flowing a Pu back extraction liquid G1 into the extractor. The plurality of extractors 40 are arranged from an aqueous phase side to an organic phase side in a multistage configuration, and the loaded solvent input port 51 and the extraction solvent input port 52 are provided only on the extractor 40 of the first stage which is positioned on the outermost aqueous phase side. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
