Tritium Properties and Interaction with Material / Proceedings of the Fifth Topical Meeting on Tritium Technology In Fission, Fusion, and Isotopic Applications Belgirate, Italy May 28-June 3, 1995 / dx.doi.org/10.13182/FST95-A30585

It is shown that the Cr-Ni-Mo stainless steel with a fine-plate austenitic-artensitic structure has a high resistance to radiation swelling. The influence of small amounts of tritium (0.015 at.%) and radiogenic helium (∼2.5 appm) on the mechanical properties of the steel is analysed.
