DEVELOPMENT OF AN ENVIRONMENTALLY BENIGN REPROCESSING TECHNOLOGY - PYROMETALLURGICAL REPROCESSING TECHNOLOGY -

摘要

Present status of research and development on pyrometallurgical reprocessing technology in Central Research Institute of Electric Power Industry is described with emphasis on electrorefining and waste salt immobilization. As for the electrorefining, three different electrodes -- anode basket, solid cathode, and liquid- cadmium cathode -- have been being investigated; prismatic anode basket with faster rotation was found to accelerate metal-fuel dissolution. Morphology and collection efficiency of electrodeposited uranium on solid cathode were found to vary with ratio of cathode to anode surface area.
