COVERT TOWNSHIP, Mich. (AP) — Federal regulators say they don't expect a broken piece of metal that became stuck inside the reactor vessel at Palisades Nuclear Power Plant to cause problems for the vessel or the fuel it holds.
The plant is along Lake Michigan in Van Buren County's Covert Township, 55 miles southwest of Grand Rapids. New Orleans-based Entergy Corp. owns the plant.
The Kalamazoo Gazette (http://bit.ly/1mdGUmN ) says workers noticed the 5-inch-by-12-inch piece during a 56-day shutdown for refueling and maintenance that ended Sunday. They couldn't remove it.
The U.S. Nuclear Regulatory Commission said Monday that the metal probably wouldn't impede flow to the fuel during normal operation or an accident.
The NRC also says the structural integrity of 17 flawed control rod drive mechanism housings wasn't compromised during plant operations.
