Description

The model of fission gas release from UO2 fuel during irradiation has been modified to include the effects of the presence of grain-edge porosity on the overall level of re-solution of gas atoms from grain boundaries. The consequence of this improvement is to enhance the predicted gas release at high burn-up. (Auth.)
