Strategic recycling of fission products in nuclear fuel cycle as for hydrogen production catalyst

Ozawa, Masaki; Fujita, Reiko*; Koyama, Shinichi ; Suzuki, Tatsuya*; Fujii, Yasuhiko*

Catalytic Electrolytic extraction method has been studied as a separation tool for rare metal fission products, RMFP in the spent nuclear fuel. In an employed CEE process, Pd$$^{2+}$$ cation itself would not only be easily deposited from various nitric acid solutions, but enhance also the deposition of co-existing RuNO$$^{3+}$$, ReO$$_{4}$$$$^{-}$$ and $$^{99}$$TcO$$_{4}$$$$^{-}$$ by acting as a catalyst. The quaternary-, Pd-Ru-Rh-Re, deposit Pt or Ti electrode, fabricated by CEE, suggested the highest cathodic current corresponding to the hydrogen generation reaction in both alkaline solution and sea water. Advanced ORIENT Cycle, where ion exchange chromatography using tertiary pyridine resin and the CEE employ as mainstay separation technology, will enhance separation and utilization of actinide and fission product, and thus be expected to realize ultimate reducing radioactive wastes.
