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.

Built in 1959, NS Savannah (NSS) was the world's first nuclear-powered merchant ship and served as a signature element of President Eisenhower's Atoms for Peace program. While in service, NSS demonstrated the peaceful use of atomic power as well as the feasibility of nuclear-powered merchant vessels. The vessel was retired from active service in 1970 and registered as a National Historic Landmark in 1991. NSS is currently part of MARAD's National Defense Reserve Fleet (NDRF) in retention status. This session will examine the history of the NS Savannah.
