NRC approves TerraPower construction permit
Today, the Nuclear Regulatory Commission announced that it has approved TerraPower’s construction permit application for Kemmerer Unit 1, the company’s first deployment of Natrium, its flagship sodium fast reactor.
This approval is a significant milestone on three fronts. For TerraPower, it represents another step forward in demonstrating its technology. For the Department of Energy, it reflects progress (despite delays) for the Advanced Reactor Demonstration Program (ARDP). For the NRC, it is the first approval granted to a commercial reactor in nearly a decade—and the first approval of a commercial non–light water reactor in more than 40 years.

Nuclear thermal-hydraulics has a leading role in nuclear safety and in the viability of the nuclear industry. Over the past few years, there have been numerous innovations that are enabling the design of new and advanced reactor systems while providing increased margins of safety. NURETH-20 will highlight emerging technical innovations enabled by thermal-hydraulic research including passively cooled SMRs, advanced non-LWRs, “microreactors” cooled by heat pipes, and the use of artificial intelligence in data analysis. The opening plenary will feature several top innovators in the nuclear industry and provide an opportunity for attendees to hear how thermal-hydraulics makes it all possible.
