Swelling and Helium Damage in Reactor Materials
Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1969 The production of inert gases by irradiation gives rise to various consequential effects on reactor materials such as swelling, fission product release and high temperature embrittlement. A review is presented on the production and the behavior of inert gases in reactor materials.

Helium ion irradiation induced swelling and hardening in commercial and experimental ODS steels
, 2023 The radiation resistance of two promising ferritic ODS steels, PM2000 and 15CRA-3, is studied. More specifically, the effect of helium on these materials is studied by examining the swelling and hardening after He+ implantation to ∼1 dpa at 4000 appm/dpa.
