Neutronics and activation analysis of a SS316 based experimental D-T fusion power reactor

Neutronics and activation analysis for a SS316 based experimental tokamak fusion power reactor was completed using a two-dimensional neutronics model because of its practical features. Operating and decay power densities in all reactor components were obtained. The significant increase of neutron fluxes in the vacuum duct region was revealed. Maintenance and waste management aspects of the reactor components were investigated. Impacts on these aspects due to important minor alloying elements and impurities such as Mn, Co, Mo, and Nb were addressed.
