Abstract

Atomic diffusion in nuclear oxides and carbides is a basic process controlling many phenomena during fabrication and irradiation of these nuclear fuels (e.g. grain growth, creep, sintering, fission gas behavior). For a complete knowledge of diffusion, its dependance on temperature, the effect of temperature gradients, of deviations from stoichiometry, of radiation and of chemical doping due to the ingrowth of fission products during irradiation should be known. The available knowledge for both oxides MO-(2-x) and carbides MC-(1-x) (M = U and/or Pu) is summarized and the existing gaps are discussed.
