The Kemmerer Power Station is an American nuclear power plant being built near Kemmerer, Wyoming by TerraPower. It will house one 345 MW Natrium reactor along with a thermal energy storage system able to vary its power output between 100 MW and 500 MW for load following.
The power station is the first Natrium reactor to be constructed, and the first commercial sodium-cooled fast reactor in the United States since Fermi 1 was decommissioned in 1975. TerraPower submitted its construction permit application to the Nuclear Regulatory Commission (NRC) on 28 March 2024, and construction of non-nuclear facilities began on 10 June 2024. The NRC approved Kemmerer Power Station's Construction Permit Application on 4 March 2026, issuing the first construction permit for an advanced commercial nuclear power plant in over 40 years.
