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.

The Babcock & Wilcox and United Engineers and Constructors advanced light water reactor (ALWR) design has features that will provide enhanced safety, reliability, and design margin over the current generation of commercial nuclear power plants. The B-600 ALWR is a 600-MW(electric) two-loop pressurized water reactor (PWR). A probabilistic analysis has been performed to provide early feedback to the designers to enhance the reliability of the safety systems. Based on this information, the ALWR designers have eliminated most of the features that dominate the risk profile in conventional PWRs. This has resulted in the calculated core damage frequency for the ALWR being better than the design targets.
