The I/sup 131/ activity released by UO/sub 2/ was collected in KOH and after precipitation measured with a scintillation well counter. A large part of the I/sup 131/ released immediately after heating was absorbed on the surface. Two types of diffusion processes were distinguished. The first is a diffusion through outer UO/sub 2/ layers with a small oxygen excess with an activation energy of 30.7 kcal/mole. The second process is a diffusion through the UO/sub 2/ lattice with an activation energy of 62.6 kcal/mole. (Gmelin Inst.)
