The Palisades Nuclear Power Plant in Covert has been shut down due to a water leakage issue in the Safety Injection Refueling Water Tank. The leak was estimated to be 34 gallons per day, with 79 gallons of slightly radioactive water having drained into Lake Michigan. A half-inch crack about the width of a thumbnail is believed to have been the source of the leak. Entergy Corporation, a New Orleans-based company, owns and operates the Palisades facility and has a 15-year power purchase agreement with Consumers Energy that will expire in 2021.
