Current status of development in dry pyroelectrochemical technology of SNF reprocessing

The technology of SNF management in molten salts currently developed by a group of institutes headed by RIAR has had several stages of development: basic research of uranium, plutonium and main FP properties (investigation and reprocessing of different kinds of SNF in 1960-1970); development of the equipment and implementation of the pyroelectrochemical technology of granulated U-Pu fuel production. Development of the vibropacking method and in-pile testing of vibropacked fuel pins with granulated fuel as the most 'logical' continuation of reprocessing: implementation of the technology for BOR-60 and BN-600 (1980-1990); development of closed fuel cycle elements. Checking of the technology using batches of SNF. In-pile tests. Feasibility study of the closed fuel cycle (CFC). Study of application of the technology to other objects (transmutation; nitride, cermet and other fuels) (1980-1990)
