Crack propagation takes place in the SCC regime (10−7-10−10 m.s−1) and Vickers indentation techniques probethe hardness properties of the samples. Irradiation is found to create point defects which mainly include E’ centers, Non-BridgingOxygen Hole Centers and Peroxy Radicals. β-irradiation herein invokes minor changes in the structure. A small effect of β-irradiation on SCC and hardness variations cannot be eliminated, despite minute variations in the SCC and the hardness properties. %G English %2 https://cea.hal.science/cea-01120966/document %2 https://cea.hal.science/cea-01120966/file/14barletetal14.pdf %L cea-01120966 %U https://cea.hal.science/cea-01120966 %~ CEA %~ X %~ CNRS %~ X-LSI %~ X-DEP %~ X-DEP-PHYS %~ DEN %~ IRAMIS-SPEC %~ SPCSI %~ DEN-MARCO %~ IRAMIS %~ GS-PHYSIQUE %~ DE2D
