TerraPower is a nuclear innovation company that designs and builds advanced nuclear reactors for clean energy generation. Its flagship Natrium reactor uses liquid sodium metal cooling and molten salt energy storage to deliver 345 MW of scalable power—enough for 400,000 homes—with the ability to ramp to 500 MW in minutes. The Natrium plant operates at low pressure for enhanced safety and requires approximately 50% less safety-related concrete and steel than conventional designs. The first Natrium plant is under construction in Wyoming. TerraPower also develops next-generation medical isotopes for precision cancer treatment through its TP Isotopes division. Founded in 2006 and headquartered in Bellevue, Washington, the company has raised over $1.5 billion at the Series D stage, backed by investors including the U.S. Department of Energy, Khosla Ventures, CRV, ArcelorMittal, SK, NVentures, and Hd-Hyundai. With over 1,000 employees, TerraPower is advancing both nuclear energy and nuclear medicine to address surging global energy demand and healthcare needs.
