Commonwealth Fusion publishes ARC physics basis in five peer-reviewed papers
Commonwealth Fusion Systems on June 4 published a five-paper ARC Physics Basis in a special issue of Cambridge University Press' Journal of Plasma Physics, the most detailed public scientific case yet for a commercial-scale tokamak power plant. The papers use SPARC design lessons and state-of-the-art tools to project that ARC - CFS' planned Fall Line Fusion Power Station in Chesterfield County, Virginia - can produce roughly 1.1 GW of fusion power and deliver about 400 MW of continuous net electricity to the grid, validating the physics path to first electricity in the early 2030s.
