PLYMOUTH — The Pilgrim Nuclear Power Station is operating safely, according to a report based on a special weeklong federal inspection conducted in January, the first of three planned this year. Inspectors, however, did bring up a flaw in an emergency cooling system that had been known but not addressed for nearly a year.
