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.

Neutron fluence-to-organ dose conversion coefficients (DCCs) were calculated for a Reference Korean-adjusted male voxel model, HDRK-Man, for some standard irradiation geometries of external neutron beams using the Monte Carlo radiation transport code MCNPX. The calculated values were compared with those for other models. The results show that HDRK-Man provides consistent results for the DCC values considering the differences in the voxel models.
