Abstract
The release upon annealing or irradiation at high temperature of fission products (Cs) from zirconia, a candidate for inert matrix, is studied by Rutherford backscattering experiments. The work is focused on the understanding of the influence of various parameters (mainly the atomic concentration of foreign species and the damage created by an external irradiation) on the diffusion and release of Cs. The results reveal that the Cs mobility is strongly enhanced when the impurity concentration exceeds a threshold of the order of a few atomic per cent. Irradiation with medium-energy heavy ions is shown to cause a further increase of the Cs mobility.
