| Abstract Scope |
Commonwealth Fusion Systems (CFS) is developing the ARC fusion power plant, which features a molten salt breeding blanket and a replaceable integrated vacuum vessel. CFS is undertaking a multifaceted material development roadmap to design materials that will be ready for the first ARC deployment in the early 2030s. The liquid FLiBe blanket motivates a desired steady-state operating temperature of approximately 600-850°C for the structural materials of the vessel. Thus, these components must withstand significant heat and neutron flux while operating at elevated temperatures in a potentially corrosive environment. ARC’s architecture is designed such that this integrated vessel will be replaced over a plant’s lifetime, allowing on-line learning and materials optimization. CFS has developed a suite of technical solutions viable for initial fusion power deployment to target this operational regime where few materials are viable and significant gaps in performance data currently exist. |
