| Title | Partial Loss of Offsite Communications and Ens |
| Event Description | The following information was provided by the licensee via facsimile:
At approximately 05:04 CST on 01/13/2005, CaIlaway Plant became aware of a partial loss of commercial out-going offsite communication ability and the ENS, HPN, and ERDS lines. Contact [capability] was established with the NRC Operations Center via commercial phone lines. Internal and in-coming [commercial] communications are not affected and a number out-going lines are available for emergency use. Callaway is currently reassigning available out-going lines to emergency facilities. Backup communication methods to offsite State and Local agencies remains available. ENS communication will be conducted via commercial phone lines to the NRC Operations Center. At approximately 05:30 CST Callaway was notified that the communications failure was the result of a severed fiber optic cable at an unknown location. At approximately 09:45 CST Callaway was informed that approximately 4000 feet of fiber optic cable was lost when a bridge near St. Louis, MO., collapsed due to flood waters. At this time there is no estimate for the completion of repairs, but the condition is expected to last up to one week due to inaccessibility resulting from rising flood waters. The licensee has notified the NRC Resident Inspector, State, and local government agencies.
The following information was provided by the licensee via facsimile: The licensee received confirmation at 11:21 CST on 3/15/2005 that permanent repairs were completed to fiber optic lines supporting offsite communications including ENS, HPN and ERDS lines at 06:00 CST on 03/13/2005. This repair replaces a temporary repair established at approximately 14:24 CST on 1/13/2005, and includes the preventive measure of burying the lines below the river bed to prevent subsequent washouts. In addition, the original notification is being corrected to reflect that the fiber optic lines were washed-out from beneath the bridge as opposed to the bridge having collapsed as was originally reported to the licensee. The NRC Resident Inspector was updated. Notified Reg 4 RDO Farnholtz |
