Abstract
The growth of fission gas bubbles from supersaturated solution in irradiated uranium dioxide has been studied by electron microscopy under isothermal annealing conditions between 1300° and 1500°C. Measurements of the kinetics of bubble growth have enabled the diffusion coefficients of atomic xenon and krypton in irradiated uranium dioxide to be determined. The diffusion coefficients obtained may be expressed by the equation: The results obtained from the current experiments are believed to be more precise than most of those obtained using the Booth model for gas released from solid samples of irradiated uranium dioxide during a post-irradiation anneal.Keywords
