Flaws found during examinations of control rod drive mechanism housings at southwestern Michigan’s Palisades Nuclear Power Plant did not affect the safety of the plant, officials said.
Operators of New Orleans-based Entergy Corp.’s Michigan plant found the flaws in 17 of 45 housings during inspections while the facility is offline for refueling and maintenance, said officials at the Nuclear Regulatory Commission (NRC).
The mechanism housings are part of the reactor coolant system boundary. The NRC said there currently is no evidence of leakage and there’s no adverse effect on safety.
Entergy spokeswoman Lindsay Rose said plans call for replacing the 17 housings.
The plant is located on the shore of Lake Michigan in Van Buren County’s Covert Township, about 55 miles southwest of Grand Rapids.
