| Title | Disruption of Incoming and Outgoing Telephone Communciation Capability |
| Event Description | On 05/16/2006 at 0945 CDT, the control room was notified that problems with Bell South and Verizon phone services had occurred which disrupted incoming and outgoing telephone communications capability for both Unit 1 and Unit 2. Subsequent attempts from the control room confirmed that the State and County ringdown line was dead as well as the Emergency Notification System line. It was also determined that although outgoing calls from the control room and Emergency Operations Facility via land line were possible, incoming calls could not be received. The NRC Operations Center was contacted via land line at 09:50 CDT to inform the NRC of the issue. Alternate communication via cell phone and satellite phone was established to allow incoming calls from the NRC, State and County. The NRC Senior Resident Inspector was notified of the issue.
Telephone service was restored at 13:50 CDT which re-established all normal and emergency telephone communications capability. |
