Plymouth: Pilgrim Nuclear Undergoes Biennial Refueling Outage

The Pilgrim nuclear power plant began a power reduction Sunday, marking the start of the facility’s biennial refueling outage. 

This is the 20th such refueling outage in the history of the Plymouth plant.


Plant owner Entergy said it’s investing some $70 million in the project, which includes bringing in more than 1,100 temporary workers to assist the plant’s 600 full-time employees to upgrade, replace, and inspect hundreds of pieces of equipment.

Entergy says the timing on when Pilgrim will return to the grid is business-sensitive, but spokeswoman Lauren Burm did tell WATD that past outages have lasted anywhere from four to six weeks.
