FAILURE OF ALL EMERGENCY SIRENS
"On 8/16/2016, while operating at 100% in Mode 1, routine testing of the off-site sirens for Wolf Creek was scheduled. The county dispatcher was unable to actuate any sirens. The dispatch supervisor was contacted to ensure there was not a personnel qualification issue. Both the dispatcher and the supervisor were unable to actuate any sirens, either manually or using the normal computer controls.
"Coffey county personnel, assisted by Wolf Creek personnel, determined that a battery had failed causing a fuse to blow and de-energizing the equipment needed to actuate the sirens. The battery has been replaced, the fuse has been replaced, and the system has been tested satisfactorily. The emergency sirens were restored to service at 12:20 CDT 8/16/2016.
"NRC resident has been notified.
"No plant systems were affected by this failure of notification equipment.
"The plant remained at 100% power Mode 1 throughout this event."
