Burlington ? The U.S. Nuclear Regulatory Commission is investigating procedures at Wolf Creek nuclear plant in eastern Kansas after a recent lightning strike.

The NRC said in a news release Monday that the Aug. 19 lightning strike knocked out all three offsite power lines to the plant near Burlington. The commission said the reactor automatically shut down after the strike, and plant systems responded as expected, with the plant’s emergency diesel generators kicking in.

The NRC said it will be evaluating the sequence of events after the shutdown, which it said did not endanger the public.

The inspection was scheduled to begin Monday and take several days. A report is expected about a month after the inspection is completed.
