“…Numerous studies [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50] showed that the increase in hardness, due to dislocation effects, could be mitigated by using high atomic weighted materials; however, the increase in atomic size increased the chances of neutron activation and subsequent mass embrittlement. By using lower atomic-weighted materials, the studies showed that embrittlement could be mitigated; issues still remained with high thermalization for low-weight materials, as some of the master curves in the studies indicated 39,40 .…”

The intent of this paper is to establish the groundwork for additional research into applying nuclear-based materials for space exploration, and attempt to link computational simulations of material exposure to fusion environments with analytical and empirical-based testing of structural and shielding components in a comprehensive, multiphysics scheme. While a special emphasis is placed on the effects of neutron activation and developing a cohesive model that links computational approaches to analytical and empirical tests (especially those used in linear-elastic fracture mechanics and nonlinear approaches), this report will also examine the effects of other sources of damage such as erosion and ablation of electrode structures, which also contribute to reducing component lifetime.
