Description
Diffusion coefficient measurements were taken using trace-irradiated Simfuel specimens. Diffusion coefficients of Xe-133 in the Simfuel matrix were obtained by post-irradiation annealing tests. The simulated values of the burnup of the specimens were 27,300 MWD/MTU and 55,000 MWD/MTU. The annealing temperatures were 900 .deg. C. Oxygen potential of the atmosphere was fixed at 320 kJ/mol. Steam partial pressure was controlled by a thermostat set at 40 .deg. C. A Mixed-Gas (4%H/He) was used as a carrier gas. The released fraction of the fission gases were measured and compared with the stable condition. The temperature was low, however, fractional release rose quickly as the temperature increased. This value was similar to D at 1467 .deg. C in the stable condition
