Abstract: High temperature melt salts were used as an electrolyte in nuclear fuel dry reprocessing which can recover U and Pu from spent fuel by electro-refining and electro-winning. Russia, the United States, Japan, Korea, the European Union and some other countries are now actively developing melt salts dry reprocessing technology at present. Among them, Russia’s oxide fuel electro-winning process is one of the most classic. In this paper, the current status, technical routes and their features of oxide fuel electro-winning developed by Research Institute of Atomic Reactors were introduced.
