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.
With over 12,000 readers throughout 54 countries, Nuclear News is recognized worldwide as the flagship trade publication for the nuclear community. News reports cover plant operations, maintenance and security; policy and legislation; international developments; waste management and fuel; and business and contract award news. The magazine has been published by the American Nuclear Society since 1959.
