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.

Innovative and collaborative work has progressed nationally and internationally regarding hybrid and integrated energy systems, including those with nuclear, nonnuclear (including hydrogen), and renewable components. Optimal energy generation and prioritization strategies can be advanced using various metrics such as reliability, security, affordability, flexibility, resiliency, and sustainability. In many cases, risk and reliability methods offer insights that are difficult to obtain otherwise to evaluate coordinated use of various energy generators to meet energy demands across the electricity, industrial, and transportation sectors. This panel will discuss national laboratory and commercial industry experience, challenges and insights gained considering integrated and hybrid energy systems using risk and reliability methods. Progress in building applicable datasets and running dynamic simulations will also be discussed.
