EN

In the present paper it is assumed that the recrystallization temperature of uranium dioxide decreases with burn-up. Two opposing effects of enhancement and inhibition of irradiation damage introduced by fission effect on grain growth are described. Mathematical model of fission gas release from the UO_{2} fuel affected by grain growth is presented. Theoretical results are compared with the experimental data.
