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 damage to the Three Mile Island Unit 2 core was extensive. The accident created a central void ∼1.5 m deep, extending almost to the periphery of the core. All of the original 177 fuel assemblies showed some signs of damage. It took a total of 5 yr of data acquisition, planning, equipment design, and defueling operations to complete the removal of the damaged core.
