DOE/EA-2217: TerraPower, LLC’s Test and Fill Facility Project; Lincoln County, WY

Summary

The U.S. Department of Energy (DOE) is preparing an Environmental Assessment (EA) for TerraPower, LLC’s Test and Fill Facility (TFF) Project located in Lincoln County, Wyoming (the proposed project).

DOE is proposing to provide federal funding to TerraPower to construct and operate this facility under the Advanced Reactor Demonstration Program. The Test and Fill Facility is designed as testing site for the TerraPower Natrium reactor’s non-nuclear operating systems, particularly those relating to the design’s sodium coolant. This facility would receive, sample, process, store, and then deliver liquid sodium to areas where component tests are performed, including the planned Kemmerer Unit 1 reactor. The research conducted at this facility would serve the sodium reactor community around the world, as interest in this technology continues to grow globally. 

DOE will be the lead federal agency in the preparation of the EA.

What’s New

May 2023 - Pursuant to the requirements of the National Environmental Policy Act (NEPA), the U.S. Department of Energy (DOE) has determined that an Environmental Assessment (EA) is required to inform a decision on whether to provide federal funding to TerraPower in support of the TFF Project. The EA will identify and analyze the potential impacts to the human environment that may occur if DOE authorizes the expenditure of federal funding by TerraPower to construct and operate the TFF Project.

November 2023 – DOE released the draft EA (DOE/EA-2217) on November 2, 2023, for a 30-day public comment period. The comment period closed on Friday, December 1st, 2023.  DOE will host one public meeting on November 16, 2023, at the South Lincoln Training and Events Center in Kemmerer, WY from 5:00 to 8:00 PM MST.
