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.

Validation of thermal-hydraulic codes for system design and safety analysis is dependent on applicable and appropriately scaled experimental data. There are several scaling methodologies for justifying the use of data from small-scale facilities for simulation of large-scale reactor systems. These methods continue to be improved and extended to new situations. This panel will discuss the "art of scaling" and progress in development of scaling methods.
