Amidst talks of decommissioning in May, the Pilgrim Nuclear Power Station in Plymouth, MA, was operating at reduced power last week so crews could weld a leak found during routine maintenance earlier this month.
“Pilgrim is undergoing a planned downpower to weld a small leak on a component, a check valve, in the plant’s Feedwater system. This component is part of the system that provides water to the reactor to create steam to generate power,” said Patrick O’Brien, spokesman for Pilgrim’s owner, Entergy.
The plant was operating at 26 percent of its full capacity.
The maintenance could not be performed while the plant is fully powered, O’Brien said. Maintenance activities would not challenge the health and safety of the public. O’Brien did not say when the plant would return to full power, saying that it is business-sensitive information.
Pilgrim is scheduled to shutdown permanently at the end of May after operating for more than four decades.
