The US Nuclear Regulatory Commission (NRC) has renewed the operating licence for the Summer-1 nuclear power plant in South Carolina for an additional 20 years, a 30 June statement said.
This marks the second licence renewal for the 973-MW pressurised water reactor unit, which can now operate until August 2062.
The NRC said it had reviewed operator Dominion Energy’s application along two separate tracks: a safety evaluation report, issued in February, and a final supplemental environmental impact statement released in May.
