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.

This research evaluated the generation of uranium-doped gadolinium zirconate pyrochlore by a high-temperature sintering method. The sintering temperature and holding time were adjusted in the fabricating course. The sintered samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy. The study shows that uranium-doped gadolinium zirconate pyrochlore can be generated with sintering parameters of 1250°C and 72 h. Analysis with XRD indicates that the uranium-doped gadolinium zirconate pyrochlore has a fluorite structure.
