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.
One of the chief concerns federal regulators have historically expressed over Pilgrim is its owners’ constant failure to follow through and get deficiencies addressed. This latest transgression involved a water leak in the core spray system that helps cool down the reactor after sudden shutdowns. The leak had allowed air bubbles to enter the system, which could impede water flow.
The leak, one of many glitches that occurred during the blizzard in January 2015, was identified in March of that year. Yet it wasn’t entered into the plant’s action plan until January 2016, leading inspectors from the Nuclear Regulatory Commission to write, “Entergy had not taken timely action to identify the source of the leakage and address the issue.”
