Title: First wall and divertor plate material selection in fusion reactors
Abstract: The criteria for selecting first wall materials in magnetic and inertial confinement fusion reactors are discussed. These criteria include radiation damage, compatibility, thermomechanical properties, fabricability, joining, industrial capability, the existing data base, cost, induced radioactivity, and resource availability. At present, stainless steel remains the primary choice for a structural material because of the large existing data base and industrial capability. Titanium and vanadium alloys are the primary backup materials. The influence of surface heating on the allowable neutron wall loading is described in detail for magnetic and ICF reactors. The use of divertors may permit reactors to operate with higher neutron wall loadings but heat transfer and excessive wall erosion by sputtering of the collector plates are fundamental problems requiring resolution before divectors are employed in reactors.
