Description
During irradiation, the fission products generated inside the UO2 matrix migrate to the grain boundaries by a process controlled by the irradiation temperature. In the unlikely event of an accident, those fission products which have reached the grain boundaries will be the first to be released from the bulk UO2. They may be released by different mechanisms depending on the accident sequence. The inventory available on the grain boundaries thus is an important component of the source term and its released history. (author). 6 refs., 10 figs
