TerraPower Nuclear Power Plant and Nuclear Waste Storage Expansion in Wyoming

planned

The project involves the building of a TerraPower nuclear power plant in Kemmerer, Wyoming, first announced in 2021, along with proposed legislation that could multiply nuclear waste storage sites across the state. The legislation would allow reactor manufacturers to maintain waste facilities in-state, placing new spent-fuel storage facilities under the Industrial Development Information and Siting Act. The Wyoming Department of Environmental Quality would review financial assurances for decommissioning, and any abandoned spent fuel would revert to the U.S. Department of Energy's responsibility. The project is part of a broader nuclear production agenda fast-tracked by President Trump, including a 240-day study on nuclear waste storage.
