In the framework of the European project PERFECT, dealing with the modelling of irradiated material behaviour, well controlled irradiations have been performed at 300 C for doses ranging from 0.025 to 0.2 dpa. At this stage, four modelalloys (Fe, Fe–C, Fe–0.1 wt%Cu, Fe–0.3 wt%Cu) have been investigated by Coincidence Doppler Broadening of positron annihilation radiation (CDBAR), a well established tool for studying defects in materials. The results demonstrate the effect of Cu on the matrix damage accumulation under neutron irradiation.
