EVALUATION OF CANDIDATE BLANKET MATERIALS FOR FUSION-REACTOR BLANKET APPLICATIONS

This paper summarizes the primary candidate materials currently considered for major components, viz. , structure, breeder, coolant, etc. Compatible combinations of materials that offer the most potential for satisfactory performance and the projected ranges of operating parameters are indicated. Critical properties of the candidate materials that limit blanket performance are defined and the areas of greatest uncertainty are identified. General characteristics of the materials systems that are potentially favorable or unfavorable for the specific application are evaluated. Based on the above assessment, a perspective of the relative importance of various materials limitations and design criteria on the projected performance and blanket lifetime is presented.
