Abstract:

Pyroelectrochemistry is one of the most prospective approach for reprocessing spent nitride nuclear fuel (nitride SNF). It includes the anode dissolution of the SNF pellets in the (LiCl-KCl)eut melt with subsequent electrochemical separation of U, Pu, Np, Am from other constituents. In the present work, the experimental results and theoretical evaluation of electrical conductivity and some other properties (density, viscosity, liquidus line) for the LiCl-KCl molten eutectic containing chlorides of uranium, plutonium and fission products (Cs, Nd, Ce, Ba, La, Pr, Sm, Am, Sr and others) are presented. These data are required for the creation of general model for electrolyzer operation and for the development of complied technological equipment. The compositions of simulated nuclear fuel consisted of 3-6 components. Properties of which are similar to properties of real SNF were proposed. This research was partially supported by the Russian Ministry of Education and Science through Targeted Federal Program (project number: 14.607.21.0084). Keywords: SNF reprocessing, pyroelectrochemistry, molten chlorides, electrical conductivity, density evaluation.
