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.

R&D and actual practical power plant construction are worlds apart. It's extremely questionable that cutting off funding to fusion would have changed any opinions on nuclear. Govts didn't abandon nuclear due to a lack of technology, it was mainly FUD by lobbyists.

If the goal is to get off fossil fuels ASAP

Problem is, that was never the goal for the people in power, it could have been accomplished easily.
