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.
Edited by Dr. Farzad Rahnema, Nuclear Science and Engineering (NSE) is the first and oldest peer-reviewed journal in its field, published by ANS since 1956. Printed twelve times a year, NSE is widely recognized as an outstanding source of information on fundamental and applied research in all scientific areas related to the peaceful use of nuclear energy, as well as on applications of nuclear particles and radiation.
Authors: Publication of articles in NSE is free of charge. Optionally, open access publication is available for a fee.
