Abstract: Radiation damage behavior of structural materials is very important in design of a fusion-fission (hybrid) reactor. Different types of alloys have been considered to be used under fusion neutron environment. In this study, main radiation damage parameters (displacement per atom (DPA) and helium production) on three different refractory alloys, namely W-5Re, TZM (Mo alloy) and Nb-1Zr used as structural material in a hybrid reactor were found. Neutron transport calculations were performed with the help of SCALE4.3 System by solving the Boltzmann transport equation with code XSDRNPM. According to numerical results, W-5Re alloy showed the best performance with respect to radiation damage. Furthermore, replacement of investigated materials will be required frequently due to their radiation damage values during reactor life (? 30 years).
