TerraPower Breaks Ground on Advanced Nuclear Power Plant in Wyoming
TerraPower broke ground in April of 2026 on the flagship Natrium plant's Kemmerer Unit 1 in Wyoming. Anticipated to be the first utility-scale advanced nuclear power plant in the United States, the pioneering facility will feature a 345-MW sodium-cooled fast reactor with an integrated molten salt-based energy system. Each Natrium reactor will have the capacity to increase output to 500 MW for over five hours in response to peaks in demand, supplying the equivalent energy needed to power 400,000 homes.
