|Abstract:||Since a number of years a program is being conducted at the Hot-Cells of the Institute of Transuranium Elements in co-operation with the industry, in order to characterise the structural changes and the thermal-mechanical behaviour of PWR-fuels irradiated to high burnups. The data acquired up to the present show that the structural changes occurring principally at the pellet-periphery (rim-zone)  do not worsen but improve the mechanical properties of the fuel, with an expected better behaviour under pellet-cladding interaction conditions [2,3].|
