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 installation of a versatile, integrated facility for the manufacture of advanced experimental uranium/plutonium nuclear fuels has recently been completed at the Windscale Laboratory of the United Kingdom Atomic Energy Authority. The facility for enhanced throughput of fuel and pins, with a production capability of 1 tonne of pelleted fuel and 2500 fuel pin/yr in a variety of fuel geometries and cladding materials, is unique in Europe. Exceptional process flexibility is achieved by adopting the design philosophy of “hands-on” operation with the support of simple mechanical and gravitational aids to material movement to minimize operator dose uptake. Comprehensive shielding allows the handling of recycle plutonium derived from high-burnup fuel with “difficult” isotopic composition at the levels of plutonium content envisaged for advanced thermal reactor fuel designs.
