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.

Fan-Bill Cheung (PSU)
Dr. Robert (Bob) Salko performs research in the area of computational thermal hydraulics to support modeling and simulation of light water reactors and molten salt reactors. His primary focus has been on development of subchannel and system thermal hydraulics codes, which includes modeling of two-phase flow and heat transfer, coupling with other reactor modeling tools, deployment on high performance computing systems, and implementing quality assurance measures and releasing software for users in the nuclear community. Bob has been working at Oak Ridge National Laboratory for approximately ten years, where he has supported efforts in the US Department of Energy Consortium for Advanced Simulation of Light Water Reactor and Nuclear Energy Advanced Modeling and Simulation programs. Prior to that, Bob obtained his PhD in nuclear engineering from The Pennsylvania State University.
