Description

This paper aims to give a brief overview of the wide research undertaken in France in order to elucidate the potential long term evolution of spent nuclear fuels in long term storage or geological disposal. A particular emphasis is put on the last scientific results obtained and on the major scientific issue on which R and D is currently focused: the fate of helium, the RN migration within the rod (irradiation-induced diffusion) and the cladding long term creep for the closed system evolution, the kinetics of oxidation and the RN source term for the evolution in gaseous atmosphere, and the radiolytic dissolution and RN source term in presence of water.
