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.

In the nuclear fuel reprocessing plant, dissolver off-gas (DOG) is supposed to include nitrogen oxides (NOX) during the operation. An adsorption process by mineral zeolite has been studied for DOG treatment that follows a dehydration and iodine removal process. According to the results, the characteristics of the mineral zeolite hydrogenated by 1 N HCl are very favorable for this purpose. As for the actual operation, a small fraction of iodine is supposed to penetrate the I2 removal process to the NOX adsorption process. No degradation has been observed for the NOX adsorption of mineral zeolite by the presence of I2.
