The primary objective of the CHADWICK program is the development of new first-wall materials that will significantly improve the commercial viability of nuclear fusion.The CHADWICK program is comprised of three technical categories to support the program objectives. Applicants can apply to Category A, Category B, a combination of Categories A and B, or Category C, based on their expertise. Category C capability teams will support analysis and facilitate communications between Category A and B project teams and fusion power system designer end users by performing techno-economic analyses (TEA) and activation analysis of their materials products.
CATEGORY A – PLASMA-FACING COMPONENT MATERIALS: Applicants to this category will discover and validate materials that maintain room temperature ductility after significant irradiation damage and helium generation while satisfying the unirradiated thermal conductivity, plasma erosion, and tritium retention performance metrics of tungsten in fusion power system first-wall applications.
CATEGORY B – STRUCTURAL MATERIALS: Applicants to this category will discover and validate materials that maintain room temperature ductility after significant irradiation damage and helium generation while satisfying the unirradiated thermal, mechanical, and tritium retention performance metrics of RAFM steels in fusion power system first-wall applications.
CATEGORY C – CAPABILITY TEAMS: Applicants seeking to contribute an expert or specialist capability that could assist multiple Category A and/or B experimental teams in fulfilling program objectives should consider selecting Category C.
