In this work, we study the diffusion characteristics and structure of molten salt FLiNaK with dissolved CeF3 in operating temperature range molten-salt reactor. The dependence self-diffusion coefficients ions that make up mixture is represented good accuracy as a linear dependence, except for case Ce ions. As rule, Li F are more mobile than Na K significantly so slow coordination numbers their ...

Pyroprocessing of spent nuclear fuels is an electrochemical separation method where metallic fuel dissolved in a molten salt bath to allow uranium (U) and plutonium (Pu) be isolated from fission products (FPs) other impurities.
