First steps towards modelling high burnup effects in UO(2) fuel
Change in the structure of high burnup fuels is a complex phenomenon which results in the formation of subgrains, the loss of matrix fusion gas and an increase in porosity. The TUBRNP model has been developed to describe this phenomenon in UO(2). Its predictions for the depth of the Xe depleted zone, as derived from EPMA measurements, are in reasonable agreement with experiment. The model should be seen as a first step in the modelling of high burnup phenomena in UO(2) fuel.
