The problem of long-term storage of nuclear-safe ceramics (NSC) supposedly containing plutonium, transition and rare-earth metals oxides is connected first with the necessity of the plutonium isotope enhanced diffusional release prognostication at storage temperatures. For lack of experimental features on diffusion processes in NSC, our estimations are based on the literature data for thermal-activated and radiation-enhanced diffusion (TAD and RED, respectively) of U and Pu in UO[sub 2] and (U, Pu)O[sub 2] oxides. © 2000 American Institute of Physics.
