The U.S. Nuclear Regulatory Commission (NRC) has extended the expiration date of the construction permit for the unfinished Unit 2 reactor at the Watts Bar nuclear power plant to Sept. 30, 2016. The Tennessee Valley Authority, which operates Unit 1 at the plant about 10 miles south of Spring City, Tenn., requested the extension on May 17, 2012
The NRC staff’s environmental assessment of the extension request, which found no significant impact on the environment, was published in the Federal Register on Oct. 22, 2013. The agency has issued the staff’s safety evaluation of the extension, as well as an order extending the construction permit.
TVA has informed the NRC it intends to complete Unit 2 and request an operating license in 2014. The NRC will decide whether to issue a license for Unit 2 in accordance with the agency’s regulations. Unit 2, if completed, would be a 1,100 MWe, Westinghouse -designed pressurized water reactor essentially the same as the operating Unit 1.
