DEVENS, Mass., June 4, 2026
The set of five peer-reviewed papers, authored by a global team of scientists in a special issue of Journal of Plasma Physics, published by Cambridge University Press, offer a scientifically rigorous examination of CFS' commercial tokamak power plant using state-of-the-art tools and lessons learned from the design and construction of CFS' SPARC fusion demonstration machine.The analysis provides confidence that the ARC power plant will be able to continuously deliver 400 megawatts (MW) of net electricity to the grid, highlighting areas of physics that are well proven and areas where additional data from SPARC will reduce uncertainty.The ARC Physics Basis papers follow the success of the original seven papers that CFS published on SPARC in 2020 and significantly improve upon the original ARC papers that predate CFS.DEVENS, Mass., June 4, 2026 /PRNewswire/ -- Commonwealth Fusion Systems (CFS), the global leader in fusion energy, today announced the publishing of five peer-reviewed physics basis papers on the company's ARC fusion power plant in a special edition of Journal of Plasma Physics, published by Cambridge University Press. The papers, written collaboratively by a team of world-class physicists, offer an in-depth examination of the scientific foundations of the ARC power plant and confirm the key physics that'll enable ARC to continuously deliver 400 megawatts (MW) of net electricity to the grid.
