摘要：

The primary objective of this paper is to develop information associated with accident safety to guide material selection for near-first-wall uses. Various figures of merit (FOM) are formulated to compare the accident safety hazard of activation product inventories in various materials. The comparisons provide quantitative guidance for desired material compositions for those materials receiving high neutron fluence. Thus, these safety FOM should be used as the waste disposal rating to help tailor materials from the waste management standpoint. The lowest activation coolants and breeders are helium, water, lithium, Flibe (LiF-BeF2), and lithium oxide. The lowest activation neutron multiplier is beryllium. The lowest activation materials for reflectors and plasma-facing tiles are carbon, beryllium, and boron.
