Commonwealth Fusion Systems to Advance Fusion Power with SPARC and ARC Reactors
FUSION & ADVANCED NUCLEAR POWER
Commonwealth Fusion Systems is advancing fusion power through a new tokamak reactor design utilizing high-temperature superconducting magnets. The demonstration reactor, SPARC, is projected to achieve net energy production, defined as Q>1, by 2027. Following SPARC, the company plans to develop a commercial reactor called ARC, which aims to produce net electricity, a significant goal in fusion energy development as no fusion reactor has yet accomplished this.
