EMERGENCY NOTIFICATION SYSTEM AND COMMERCIAL TELEPHONE LINE PROBLEMS
"On 9/24/06 at approximately 0430 EST, the NRC Duty Officer attempted to contact the plant via the ENS (Emergency Notification System) phone for the daily plant status. Communications via the ENS phone had apparently failed, and attempts by NRC to use the commercial lines for Unit 1, Unit 2 and the Shift Manager were also unsuccessful. The plant was notified at approximately 0650 by the TVA ODS (Operations Duty Specialist) that the NRC was apparently unable to communicate with Sequoyah via the ENS phone and commercial lines. Sequoyah staff was able to communicate with the NRC Duty Officer with a commercial line, however, the ENS phone line was not functional at that time. At approximately 0700, the ENS phone was successfully utilized to communicate with the NRC Duty Officer. This event is being reported under 10CFR50,72(b)(3)(xiii), Loss of Emergency Preparedness Capabilities. An investigation will follow to determine the cause and required corrective actions."
The licensee notified the NRC Resident Inspector.
