Federal regulators who inspected a piping system problem at the Millstone nuclear power complex in Connecticut are calling it a “more than minor” safety violation, but one that won’t go on the company’s permanent record.
The Nuclear Regulatory Commission says there are no public safety issues because Millstone owner Dominion found and fixed the problem at the Unit 3 reactor in Waterford during routine maintenance in October.
NRC officials say some gas got trapped in the piping system for the reactor’s safety system.
Regulators were concerned that if there was an emergency, the gas could affect the operation of the pumps used to deliver water to the reactor vessel to keep nuclear fuel covered and cooled.
