AP, Covert Township — Federal regulators say they found a safety violation at the Palisades nuclear power plant in southwestern Michigan earlier this year. The Herald-Palladium reports the Nuclear Regulatory Commission says the violation of “low to moderate safety significance” involves measuring workers’ exposure to radiation while replacing parts between January and March. The Entergy Corp. plant is in Van Buren County’s Covert Township on the shore of Lake Michigan. The NRC says no workers appear to have received higher-than-allowed exposure. It says the violations had the potential to create safety problems. A spokeswoman says the regulator would downgrade the plant’s safety status if the preliminary finding stands. A plant spokeswoman says the company will respond to the report this week. She says the company took multiple actions to measure and limit radiation exposure.
