Description

Multicomponent composition of spent nuclear fuel (SNF) in view of the physicochemical properties of the elements and their oxides is considered. The possibility of fission product removing from SNF at the stage of thermal heating is analyzed. The values of the diffusion coefficients and activation energies of some elements for SNF diffusion parameters estimation are presented
