The Advanced Research Projects Agency – Energy (ARPA-E) is offering a Funding Opportunity Announcement (FOA) titled "Creating Hardened and Durable Fusion First Wall Incorporating Centralized Knowledge (CHADWICK)" to support research in developing innovative materials for fusion power plants. The program aims to discover first-wall materials that can withstand extreme conditions over a 40-year lifespan, focusing on improving resistance to irradiation-induced embrittlement and swelling while maintaining thermal conductivity and minimizing neutron activation. This initiative is crucial for advancing energy technology and enhancing the commercial viability of nuclear fusion. Approximately $30 million is available for grants, with individual awards ranging from $1 million to $7 million. Concept paper submissions are due by February 13, 2024, and full applications must be submitted by May 21, 2024. For more information, applicants can visit the ARPA-E eXCHANGE website or contact ARPA-E CO at arpa-e-co@hq.doe.gov.
