Damage caused by neutrons in the first wall of a fusion reactor is studied in detail for two different structural materials (Type 316 stainless steel and nimonic PE-16) in a fusion power plant design. The first-wall neutron spectrum is calculated by the ANISN code, and a dosimetric analysis is performed for both materials. Moreover, a complete study of damage (swelling and creep) during reactor life is done for type 316 stainless steel. On the basis of 1% creep strain, the lifetime of a type 316 stainless steel first wall is calculated to be {approximately} 2 yr, compared with the {approximately} 22-yr lifetime obtained for nimonic in the power plant design. In this way, the economic advantage of a superalloy, compared to stainless steel, has been confirmed.
