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 advantages of replacing obsolete analog equipment with modern digital equipment in a pressurized water reactor are presented. Several modifications to the control system are discussed in detail, with anticipated benefits. The process of rejuvenating the protection system of old 900-MW(electric) plants is described, indicating objectives, technology employed, and new system architecture.
