Assessment of structural activation in the operation of the fusion ignition experiment IGNITEX

Summary form only given. The layout of the IGNITEX facility was modeled, and the activation responses of the various candidate materials were determined. The ONEDANT code was used to simulate the neutron transport, and the REAC2 code was employed to evaluate neutron activation. Neutron cross sections for the transport calculation were derived from the VITAMIN-E library. Steel, aluminum, copper, titanium, and Inconel were analyzed as vacuum vessel materials. Both GlidCop and BeCu copper alloys were studied as magnet materials. Steel, aluminum, and fiberglass were considered as cryostat materials. Different materials for cryostat covers were investigated. It is concluded that, in selecting component materials, it is important to account for activation levels and for additional shielding requirements for hands-on maintenance
