Abstract

For a number of years a programme has been conducted on hot-cells at the Institute of Transuranium Elements in co-operation with industry, in order to characterize the structural changes and the thermal-mechanical behaviour of pressurized water reactor (PWR)-fuels irradiated to high burnups. The data acquired up to now shows that the structural changes occurring principally at the pellet-periphery (rim-zone) do not impair but improve the mechanical properties of the fuel, with predicted enhanced behaviour under pellet-cladding interaction conditions.
