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.

A helium-induced shift in the temperature dependence of swelling [PDF]
Journal of Nuclear Materials, 1979 Abstract In an annealed austenitic alloy undergoing bombardment with 4 MeV Ni ions to doses between 1 and 70 dpa at 840, 900, 950, 1025, and 1100 K, the introduction of simultaneously-implanted helium at a rate of 20 appm He/dpa moves the swelling versus temperature curve up the temperature scale by 40 to 70 K. Co-implantation of hydrogen (deuterium)
