Abstract

Abstract

Effect of fuel oxidation on fission product diffusional release is analyzed, and it is concluded that the vacancy increase due to the fuel oxidation has greater effect on the enhanced fission product release than the temperature increase due to the degradation of fuel thermal conductivity. The fission product release fractions increase with the O/U ratio, and this phenomenon is more obvious as the linear heat rate increases.
