Uranium dioxide fuel with initial grain sizes from 8 to 80 ..mu..m was irradiated at linear ratings of 50 to 65 kW/m to a maximum burnup of 230 MW.h/kg U (10,000 MW.d/metric ton U). At a linear power of 50 kW/m, where grain growth is not significant, a large initial grain size reduced fission gas release; above 50 kW/m, the results were inconclusive, but a large initial grain size appeared less effective in reducing release.
