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 nonlinear optimization program was used to fit the model equation to the experimental equilibrium data of a thorium-nitrate/nitric-acid-1-M di-n-heptyl sulfoxide (DHPSO) 1,1,2-trichloroethane (TCE) system successfully. The extraction equilibrium curves for this system obey Langmuir type. The product of parameters A and K is the maximum extraction distribution coefficient that can be used to compare the extraction power of 1 M DHPSO-TCE with respect to Th(NO3)4 at various aqueous acidities.
