Commonwealth Fusion is advancing its fusion reactor plans with peer-reviewed papers detailing the physics behind its 400 MW ARC reactor design. The company's approach uses high-temperature superconductors to create stronger magnetic fields, enabling smaller reactor sizes and faster development than traditional projects like ITER. The papers outline current models and identify knowledge gaps that will be addressed by their SPARC tokamak, scheduled to begin operations next year.
Background
Fusion power has long been pursued as a clean energy solution, with ITER being the largest international fusion project. However, its lengthy timeline has prompted private companies like Commonwealth Fusion to pursue alternative approaches using newer technologies like high-temperature superconductors to accelerate development.
