| Abstract | Deuterium retention of low activation ferritic steel, F82H, was studied by deuterium ion irradiation and followed by thermal desorption spectroscopy. When the fluence was 1 × 1018 D/cm2, the retained amount of deuterium for the F82H exposed to the atmosphere was 3 ×1016 D /cm2 which was one order of magnitude larger than that of the F82H mechanically polished. A large amount of deuterium was trapped in a thick oxide layer. The retained amount became comparable to that of the F82H mechanically polished when the fluence was 7× 1018 D/cm2 The retained amount of deuterium was roughly comparable to that of 316L SS and one order of magnitude smaller than that of graphite. The sputtering yield was also examined, and the obtained value was comparable to that of pure iron. These data are useful to understand the plasma surface interactions for a fusion device with plasma facing walls made by ferritic steel. |
