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 new approach for solving electron transport problems by the Monte Carlo method has been developed. The present approach uses pseudo-reduced single elastic and inelastic scattering cross sections instead of the multiple scattering distributions commonly used in conventional Monte Carlo calculations. Transmission and albedo factors for 1- and 0.5-MeV electrons normally incident on materials of low and high atomic number (aluminum and gold) have been obtained and compared with earlier results. The agreement is reasonably good. The present method is simple and considerably reduces data storage in the computer's memory.
