A computer program is described which calculates the behavior of UO2 pellet fueled elements during irradiation. Whenever possible, prediction and experimental observation are compared to verify that the models developed for calculation are reasonable. The interaction of variables when operating with high internal fission gas pressures (and, hence, reduced fuel-sheath heat transfer coefficient) is emphasized.
