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 results through 1988 of the postaccident inventory and distribution of selected radionuclides within the Three Mile Island Unit 2 (TMI-2) reactor system are presented. Best-estimate inventories are presented for krypton (85Kr), cesium (137Cs), iodine (129I), antimony (125Sb), strontium (90Sr), ruthenium (106Ru), and cerium (144Ce). This inventory accounting includes all repositories in the TMI-2 reactor system. The accountability for principal radionuclides includes 144Ce (105%), 90Sr (93%), 137Cs (95%), and 85Kr (91 %). The accountability for radioiodine is similar to that for cesium. The principal repositories for cesium and iodine, and the noble gases, are the reactor building, and the reactor vessel for all other radionuclides.
