Description
Since the LWR operation mode changed from annual to extended/high burn-up fuel cycles in the late 1980s, more attention has been paid to fission gas release phenomena. There have been reports that fractional fission gas release is even accelerating with increasing burn-up. Therefore, for the development of high performance fuels, fission gas release is considered. In this study, two-stage two-step model is developed which incorporates two stage diffusion processes, grain lattice and grain boundary diffusion, coupled with the two step burn-up factor in the low and high burn-up regime
