Research Abstract |
The effects of surface damage induced in advance on hydrogen isotope desorption/retention properties of reduced activation ferritic steel were investigated. The reduced activation ferritic steel, F82H, was irradiated to helium or hydrogen ions/plasma. Then, the relation of the induced surface damage with properties of the hydrogen isotope retention/desorption was examined. The introduction of surface damage layer and/or surface modification such as change in impurity distribution by plasma/ion irradiation significantly affected the properties of hydrogen isotope retention/desorption of the ferritic steel.
