  "abstract": "Fission gas release might play a role in the fragmentation of nuclear fuel during a Loss of Coolant Accident. Using MERARG facility, we studied the kinetics of fission gas release during the heat treatment of several segments taken out of a fuel rod irradiated 6 cycles in a commercial reactor up to an average burn-up of 67 GWd/tU. The samples exhibited the same gas release with one burst release at around 700°C and another one at around 1200°C. We then studied gas release in isothermal conditions, by imposing a temperature plateau when gas burst was near its maximum. Two different kinetics for gas release were observed: the one during the plateau at 700°C is much faster than the other during the plateau at 1200°C.",
