The Nuclear Regulatory Commission has approved Dominion Energy’s application to renew the Surry nuclear power plant’s operating licenses for an additional 20 years. The renewed licenses authorize the extension of reactor operation at the two-unit plant from 60 to 80 years.

The disturbingly long list of U.S. nuclear plants prematurely closed in recent years will get even longer tonight when the last reactor at the Indian Point Energy Center, Unit 3, powers down for the final time. The shutdown, scheduled for 11 p.m. local time, will mark the end of nearly 60 years of zero-carbon electricity generation at the Buchanan, N.Y., facility.
