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 method was proposed to transfer the efficiency of gamma-ray spectrometers calibrated with a standard water source to suit other samples. In our method, it is not important to know the concentration of the major elements of the sample to be measured. This gives a special importance to our method for low-energy photon detection where the self-absorption is strongly material dependent.
