Bill Gates-Backed 345 MWe Advanced Nuclear Reactor Secures Crucial US Approval

Long-time Slashdot reader schwit1 shares this article from Interesting Engineering: Bill Gates-backed TerraPower's innovative Natrium reactor project in Wyoming has cleared a critical federal regulatory hurdle. The US Nuclear Regulatory Commission (NRC) has successfully completed its final Environmental Impact Statement (EIS) for the project, known as Kemmerer Unit 1, and found no adverse impacts that would block its construction. The commission officially recommended that a construction permit be issued to TerraPower subsidiary USO for the facility in Lincoln County. This announcement marks a significant milestone, making the Natrium project the first-ever advanced commercial nuclear power plant in the country to successfully complete this rigorous environmental review process... The first-of-a-kind design utilizes an 840 MW (thermal) pool-type reactor connected to a molten salt-based energy storage system. This storage technology is the plant's most unique feature. It is designed to keep the base output steady, ensuring constant reliability, but it also allows the plant to function like a massive battery. The system can store heat and boost the plant's output to 500 MWe when demand peaks, allowing it to ramp up power quickly to support the grid. TerraPower says it is the only advanced reactor design with this unique capability. The Natrium plant is strategically designed to replace electricity generation capacity following the planned retirement of existing coal-fired facilities in the region. While the regulatory process for the nuclear components continues, construction on the non-nuclear portions of the site already began in June 2024. When completed, the Natrium plant is poised to be the first utility-scale advanced nuclear power plant in the United States. The next step for the construction permit application is a final safety evaluation, which is anticipated by December 31, 2025, according to announcement from TerraPower, which notes that the project is being developed through a public-private partnership with the U.S. Energy Department. "When completed, the Natrium plant will be the first utility-scale advanced nuclear power plant in the United States."
