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.

A simple method to measure the change in length of a silicon carbide temperature monitor due to annealing is presented. A differential dilatometer is used to detect the change in length of an irradiated specimen as the temperature of the specimen is raised in steps. The results obtained by this step-heating dilatometry method are in good agreement with measurements obtained with an X-ray diffractometer and a micrometer.
