 note = {A reduced-activation ferritic/martensitic (RAFM) steel is expected as a blanket structural material in a nuclear fusion DEMO reactor. The blanket structural material suffers from fusion neutron bombardments which induce a huge production of irradiation defects such as vacancies, interstitials, helium atoms, and their clusters. Especially helium is known to strongly enhance cavity swelling and high temperature intergranular embrittlement. For a design of the DEMO reactor, it is necessary to develop a methodology that can mechanistically interpret the existing experimental irradiation data and predict the helium effects in the fusion DEMO environment. The objective of this study is to mechanistically understand the helium effects on the cavity swelling in RAFM steel, focused on the nucleation and growth processes of helium bubbles under a wide range of irradiation conditions: temperature, dpa rate, and helium production rate., 20th International Conference of Fusion Reactor Materials},
