| 简介 |
The present invention relates to a method for refining a waste, generated in a process of decontaminating a high-level radioactive waste to an intermediate-level radioactive waste, to a low-level radioactive waste. According to the present invention, the method for refining a waste, generated in a process of decontaminating a high-level radioactive waste to an intermediate-level radioactive waste, to a low-level radioactive waste, with respect to zirconium metal including an actinide element group, molten salt including an actinide element group and rare earth element group ions, and an actinide element group, generated in an intermediate-level decontaminating process, comprises the steps of : (1) electrolytically refining the zirconium metal including an actinide element group based on LiF-KF eutectic salt; and (2) electrolytically withdrawing and oxidizing the molten salt including an actinide element group and rare earth element group ions by using liquid bismuth and bismuth chloride.(AA) PyroBlue process(BB) Nuclear transformation annihilation furnace(CC) Low-level radioactive waste(DD) Actinide element group(EE) Step of decontaminating a high-level radioactive waste to an intermediate-level radioactive waste(FF) Zirconium (including an actinide element group)(GG) Molten salt including rare earth element group ions (including an actinide element group)(HH) Low-level electrolytic step(II) LiF-KF-based electrolytic refining(JJ) Molten salt/Liquid Bi contact electrolytic withdrawal-oxidizing extraction(KK) Molten salt including an actinide element group(LL) Low-level radioactive zirconium(MM) Low-level radioactive rare earth element groupCOPYRIGHT KIPO 2018 |
