A theoretical model (FASTGRASS) has been used for predicting the behavior of fission gas and volatile fission products (VFPs) in UO2-base fuels during steady-state and transient conditions. This model represents an attempt to develop an efficient predictive capability for the full range of possible reactor operating conditions. Fission products released from the fuel are assumed to reach the fuel surface by successively diffusing (via atomic and gas-bubble mobility) from the grains to grain faces and then to the grain edges, where the fission products are released through a network of interconnected tunnels of fission-gas-induced and fabricated porosity.

Proceedings of a symposium organized in co-operation with the United States Nuclear Regulatory Commission and Battelle Columbus Laboratories, Columbus, Ohio, from 28 October to 1 November 1985. Five topics related to source term evaluation were selected for review and discussion, namely in-vessel release, retention in the primary circuit, ex-vessel release, retention in the containment and release from the plant.
