| Abstract: | Conclusions The experimental data give evidence of a retardation in the growth of equiaxial grains when oxide fuel is irradiated. This
retardation in grain growth can be explained as being due to the formation of short-lived defect structures on the grain boundaries
under the action of irradiation.
An analysis of a broad spectrum of experimental data indicates that a model based on this hypothesis correctly predicts the
growth of equiaxial grains in a wide range of temperatures, irradiation intensities, and fuel depletions.
