Commonwealth Fusion Systems (CFS) has verified the core plasma physics assumptions for its upcoming ARC fusion power plant following a peer-reviewed study published in the Journal of Plasma Physics.
The research confirms the ARC reactor design aligns with known physics, allowing the company to shift its focus toward detailed hardware engineering…
According to the validated models, the ARC plant will produce approximately 1.1 gigawatts (GW) of fusion power to generate 400 megawatts (MW) of net electricity for the grid…
CFS engineers are using this simulation framework to optimize upcoming design iterations, adjusting dimensions like tokamak width and divertor length to refine reactor performance before manufacturing begins.
It’s 36% net positive. So it uses the rest to maintain the fusion reaction, but you still get energy out of it.
