THE DEVELOPMENT OF METAL RECYCLING TECHNOLOGY FOR DECOMMISSIONING WASTE

Nuclear Power Engineering Corporation (NUPEC) has been developing techniques of metal recycling for decommissioning waste, under the consignment by the Ministry of Economy, Trade and Industry (METI) of Japan. To separate activated nickel and cobalt from iron pyro-metallurgically, three methods are tested, The High-Temperature Solvent Extraction Method, The Oxygen Sparging Method and The Molten Salt Electrolysis Method. This paper describes the test results and process evaluations of these methods.
