Abstract
This paper presents the calculated irradiation response in displacements per atom and gas production values of a number of elements and metal alloys in a fusion reactor first-wall neutron spectrum. The gas production rates for new alloy compositions can be synthesized from these results, and all comparisons are thus kept on a consistent basis. The sensitivity to the nuclear data base used and to the exact neutron spectrum is found to be greatest in the helium production rates. This helium production value in some alloys may also be sensitive to composition. In type 316 stainless steel variations of +-9 percent are possible for compositions within the specification range.Keywords
