| Abstract Scope |
As nuclear and plasma physics continue to advance towards higher scientific gain from fusion reactions, the major challenge becomes ensuring these fusion reactions can be sustained to achieve commercial viability. One engineering challenge is the survivability of the plasma facing and structural material in a commercial fusion power plant. Existing materials qualified for use in nuclear environment by ASME BPVC Section II are not expected to last more than a few years for fusion plants. New materials are needed to meet the specific performance demand of fusion power plants. ARPA-E’s program for Creating Hardened and Durable Fusion First Wall Incorporating Centralized Knowledge (CHADWICK) tackles this challenge via projects that increase irradiation resistance via grain boundary engineering, powder metallurgy, solid state manufacturing, and new material discovery. The goal of the program is to accelerate the discovery and development of new materials to meet commercial fusion power plant requirements within three years. |
