[en] Microstructure of new construction steels for advanced reactor systems with different type of structure: oxide dispersion strengthened steel - ODS Eurofer (20% Cr), ferritic-martensitic steel Eurofer 97 and austenitic steel NF 709 were studied by positron annihilation lifetime spectroscopy. Samples were measured before and after helium ion implantation (He"+); therefore microstructure changes and radiation resistance to alpha particles of these steels were observed. Defect accumulation due to the radiation treatment was assumed in all investigated materials; therefore positron mean-lifetimes will increase up with notable change. The paper compares radiation damage of different type of structure and point out to the most radiation resistant structure/material from the investigated ones. (authors)
