Pilgrim nuclear power is back to full power following a brief slowdown for scheduled maintenance.
Power was reduced at Pilgrim Nuclear Power Station to allow for a routine thermal backwash performed five or six or times a year to remove mussel growth from the plant’s main condenser, said Patrick O’Brien, spokesman for plant operator Entergy Corp.
O’Brien said crews performed other scheduled maintenance and testing as well.
The power reduction comes less than two weeks after the troubled plant returned to full power following its third shutdown in what will be its last full calendar year of operation.
The plant, which is slated to cease operations by the end of May 2019, had been offline for nearly a week in late April and early May so crews could fix a problem with feedwater regulator valves.
Before that, Pilgrim spent 43 days disconnected from the grid in March and April amid a series of storms, mechanical problems and maintenance work. It was also taken offline for six days in January after a transmission line was cut off 25 miles from the plant during a major snowstorm
