PARTIAL LOSS OF OFFSITE COMMUNICATIONS AND ENS

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.

ENTRY INTO TECHNICAL SPECIFICATION REQUIRED SHUT DOWN DUE TO LOSS OF ESSENTIAL BUS

The following information was provided by the licensee via facsimile:

"At 0849 hours on January 13, 2005, during testing of Essential Bus D1 (Undervoltage Units monthly functional test) [the] Potential Transformer secondary fuse blew. This caused an Essential 4160 VAC Bus D1 undervoltage condition. Emergency Diesel Generator #2 auto started due to the undervoltage condition on Essential Bus D1. This auto start of EDG #2 is reportable IAW [in accordance with] 10CFR50.72(b)(3)(iv)(a).

"[The licensee entered] into Technical Specification 3.0.3 with a loss of Essential 4160 VAC Bus D1 [with] plant shutdown required within 1 hour if the Essential Bus and DC battery chargers 2P and 2N are not restored.

"At 0949 hours, [the licensee] commenced plant shutdown to comply with Technical Specification 3.0.3. The initiation of the plant shutdown is reportable IAW 10CFR50.72(b)(2)(i).
[At] 1049 hours, [the license] re-energized Essential 4160 VAC Bus D1 and verified battery chargers 2P and 2N energized.

"[At]1051 hours, [the licensee] exited Technical Specification 3.0.3 and stopped plant shutdown.

"[The licensee also noted that] at 0855 hours, EDG #2 was shutdown when the #2 Service Water pump did not start. [At] 1144 hours, Service Water Pump #2 [was started and the licensee] declared Service Water Loop 2 OPERABLE."

The license has notified the NRC Resident Inspector, will notify local government agencies, and expects to make a press release.

OFFSITE NOTIFICATION DUE TO FLOOD WATCH

The following information was provided by the licensee via facsimile.

"On January 13, 2005, at 1300 [CST] hours, Clinton Lake level reached 694 feet - 0 inches (mean sea level). Normal lake level is 690 feet - 0 inches. Per Clinton Power Station (CPS) procedure 4303.02, "Abnormal Lake Level." the CPS Main Dam - Emergency Action Plan requires that a "Flood Watch" be declared. This resulted in a notification to the DeWitt County Sheriff's Department that occurred at 1218 hours. A four-hour notification to the NRC is required due to the notification of an offsite government agency. (Reference 10CFR50.72(b)(2)(xi)). At 1235, the lake level was 694 feet - 3 inches and continuing to rise due to the heavy rains received in the area for the past several hours. Sandbagging has begun as a precautionary measure in the screen house, per CPS procedures."

The licensee notified the NRC Resident Inspector.
