The shutdown at the Plymouth plant occurred as the reactor was being returned to service May 10 from a refueling and maintenance outage.
The three-member NRC team starting Monday will review plant operator performance and decision-making, the effectiveness of owner Entergy Nuclear’s response to the event, and any actions taken by the company to prevent a similar event.
There was no danger from the shutdown that happened when the reactor was generating at 4 percent capacity.
A report on the inspection is expected to be issued within 45 days after the review’s completion.
Pilgrim is conducting its own review.
