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.

Articles are hosted by Taylor and Francis Online.
The fabrication of mixed uranium-plutonium oxide fuel for the U.K. Fast Breeder Reactor Programme is discussed, and the experience gained by the United Kingdom Atomic Energy Authority and British Nuclear Fuels pic over the past 25 yr is used to identify aspects of the manufacturing routes that influence irradiation performance and subsequent recycle. The design of a small-scale production plant for fast reactor mixed-oxide (MOX) fuels is discussed, and its conversion to produce 8 tonne/yr (heavy metal) thermal MOX fuel is outlined.
