Federal regulators have cited Dominion, the owner of the Millstone nuclear power plant complex in Waterford, for a power spike last year.
Dominion is investigating the cause of a power surge last year at its Unit 3 reactor that resulted in federal regulators citing the company for not responding quickly enough to the situation.
The incident was one of three “more than minor” violations in a federal Nuclear Regulatory Commission quarterly inspection report released this month.
A Dominion spokesman says reactor power surged by about 2 percent on Nov. 10 and there was never any threat to public safety or the routine safety function of the reactor.
