NRC Issues First Commercial Reactor Construction Approval in 10 Years For TerraPower in Wyoming
ROCKVILLE, Md. The Nuclear Regulatory Commission has authorized the staff to issue TerraPowers subsidiary, US SFR Owner, a construction permit for the companys Kemmerer Power Station Unit 1 commercial nuclear power plant in Kemmerer, Wyoming.
This is a historic step forward for advanced nuclear energy in the United States and reflects our commitment to delivering timely, predictable decisions grounded in a rigorous and independent safety review, NRC Chairman Ho Nieh said.
This is the first commercial reactor the NRC has approved for construction in nearly a decade and the first approval for a non-light water reactor in more than 40 years. NRC staff finished their technical review of this new design in less than 18 months.
Following a streamlined mandatory hearing process, the Commission
authorized its Office of Nuclear Reactor Regulation to issue the permit, having found the staffs review of the Kemmerer application adequate to make the necessary regulatory safety and environmental findings. The staff expects to issue the permit soon.
