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.

The natural transmutation or decay process is governed by a system of ordinary differential equations known as Bateman equations. When the chain involves different decay branches, solutions to the Bateman equations can be complex. In our recent studies, we have developed a set of algorithms for accurately computing multinuclide decays. These algorithms have been implemented as a prototype software platform named Decay Interaction Visualization and Analysis (DIVA) for supporting multinuclide decay calculation, visualization, and analysis.
