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.
