Description

The diffusion coefficient of Xe-133 was obtained from an annealing test. The specimens were made from a UO2 single crystal powder with natural enrichment and weight and grain size were 300mg and 23μm. Oxygen potentials were obtained from oxygen sensor. Then, O/M ratios of three specimens were 2.0005, 2.16 and 2.01, respectively. Released fractions were obtained from both results of gamma scans and quantitative analysis with MCNP code. Activation energy of the diffusion coefficient in near stoichiomeric UO2 was about 310 kJ/mol. Diffusion coefficient was observed to be higher with O/M ratio(300 times at 1600 .deg. C). Comparing with other data, data of near stoichiometric UO2 are in agreement with them
