Abstract
The nuclear fission is a main device of energy production to sustain the development over the 21st century in the world. The recycling of fissile materials must be a key issue for keeping the use of nuclear energy. Pyrochemistry/pyrometallugy is one of potential devices for future nuclear fuel cycle. Not only economic advantage but also environmental safety and strong resistance for proliferation are required for the fuel cycle. In order to satisfy the requirement, actinides recycling used pyrochemistry with molten salt of LiCl-KCl, which could be implemented to light water reactor and fast breeder reactor fuel cycles, has been an issue of current interest. Electrorefining for U and Pu separation and reductive-extraction for TRU separation have been studied over decade. Reduction process of oxides in molten LiCl has been also examined by use of actinide oxides. The application of this technology on reprocessing of oxide and metal spent fuels and on separation of actinides in high level liquid wastes should improve the present nuclear fuel cycle system.
