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 radiologically hostile environment resulting from the Three Mile Island Unit 2 accident required the application of various techniques to provide effective personnel contamination protection. A wide variety of protective clothing was utilized throughout the cleanup, ranging from cloth clothing to heavy-duty firefighter’s gear for work in areas containing highintensity beta contamination. In prescribing protective clothing, the overall risk to the worker was considered to ensure that the intended task could be performed at maximum efficiency. Through the application of appropriate protective clothing, skin contaminations were effectively minimized.
