摘要: The Korea Atomic Energy Research Institute (KAERI) has been developing pyroprocessing technology for recycling useful resources from spent fuel since 1997. process includes pretreatment, electroreduction, electrorefining, electrowinning, and a waste salt treatment system. This paper briefly addresses unit processes related innovative technologies. As the electroreduction step, stainless steel mesh basket was applied adaption of granules uranium oxide. designed ready handling transfer feed material. A graphite cathode used continuous collection dendrite in electrorefining enhances throughput electrorefiner. particular type stirrer to inhibit spill-over at liquid Cd crucible. residual actinide recovery system also tested recover TRU tracer. In order reduce volume, crystallization method is employed Cs Sr removal. Experiments on were successfully, based results, engineering-scale equipment PRIDE (PyRoprocess Integrated inactive DEmonstration facility).
