(AP) — The utility that runs the Cooper nuclear power plant in southeast Nebraska must persuade regulators it has improved the way workers respond to problems.

Nuclear Regulatory Commission officials plan to meet on June 26 with the Nebraska Public Power District to discuss the concerns inspectors identified last year.

The NRC says that Cooper’s overall performance is acceptable, but regulators to know what NPPD has done to improve the way problems are analyzed and addressed.

NPPD spokesman Mark Becker says the plant’s managers are working to correct this issue, but he emphasized that Cooper continues to operate safely.

Cooper is located on the Missouri River about 70 miles south of Omaha.
