For the third time this year, the Pilgrim Nuclear Power Station has shut down.

The 45-year-old plant in Plymouth stopped operating last Friday as a result of a “potential issue with . . . one of our two feedwater regulation valves,” said Patrick O’Brien, a spokesman for the plant. The valves allow operators to control the amount of water that enters the reactor. The water, which is converted into steam, turns the turbine to generate power.

“In accordance with station procedure, operators removed the plant from service to address the issue,” O’Brien said. “Our focus is always on the safe, reliable operation of Pilgrim station and we address issues that arise with that in mind.”

The most recent outage, which ended last month after 43 days, was the result of the plant’s need to replace a transformer. O’Brien declined to say when the plant would resume operations.
