The federal grant notice titled "Creating Hardened and Durable Fusion First Wall Incorporating Centralized Knowledge (CHADWICK)" is being offered by the Advanced Research Projects Agency Energy (ARPA-E). This grant opportunity falls under the category of Science and Technology and other Research and Development. The funding instrument type is a Procurement Contract.

The purpose of this grant is to support the discovery and testing of novel, first-wall materials that can maintain design performance over the target 40-year design lifetime of a fusion power plant. In fusion power systems, the first wall plays a crucial role in containing the fusion reactions, bearing the mechanical load, and protecting the components from extreme heat and highly energetic particles. However, the first wall's safety and structural performance are compromised over time due to exposure to high-energy neutrons and heat flux.

The CHADWICK program aims to address this challenge by developing new materials that can withstand the intense neutron environment and maintain key metrics in a fusion first-wall environment. These metrics include room temperature ductility after 50 displacements per atom (dpa) of irradiation damage and helium generation, high thermal conductivity to remove up to 10 megawatts per square meter (MW/m2) of heat, activation below 10,000 Sieverts per hour (Sv/hr) to enable remote handling, swelling below 1% to maintain dimensional stability, and lower tritium retention and plasma erosion compared to current state-of-the-art materials.

By discovering and producing such materials, the lifetime of the first wall in fusion power plants can be significantly extended, leading to the deployment of sustained and economical fusion energy. The grant opportunity provides detailed information on how to apply through the ARPA-E eXCHANGE platform.

The close date for concept paper submissions to this FOA is February 13, 2024, at 9:30 a.m. Eastern Time.
