FAILURE OF ALL REFUELING WATER STORAGE TANK LEVEL INDICATORS
"Event or condition that at time of discovery could have prevented the fulfillment of the safety function (FWST [Refueling Water Storage Tank] Auto Swap over).
"Refueling Water Tank Level indication for all three channels failed high due to failure of automatic heat tracing which resulted in instrument lines freezing. Exited condition at 0342 hours on 1/24/03."
The NRC Resident Inspector will be notified.

LOSS ENS AND OFFSITE COMMUNICATION
"A major telephone line between Plant Hatch and Uvalda [GA] was damaged (cut) causing a major loss of communication system.
"The ENS was inoperable, but the NRC could be notified by commercial line. The Prompt Notification (NOAA radios) was inoperable. Approximately one half of the ability to call offsite was lost (one half of the lines).
"Note: The Prompt Notification System (NOAA radios) were returned to service at 1115 [EST]. Total out of service time was 45 minutes."
The licensee notified the NRC resident inspector.
* * * * UPDATE RECEIVED VIA FAX AT 1601 EST ON 1/24/03 FROM BARRY COLEMAN TO MIKE RIPLEY * * * *
"We have a new update from Bell South. The line that was cut was not between the plant and Uvalda [GA]. They're repairing the cable now and expect all circuits to be restored by 4:00 PM. Apparently, some land clearing crews were working near the buried fiber between the plant and Baxley [GA] and severed BellSouth's fiber.
"NOAA Problem - NOAA was already running on the secondary transmitter fed from Baxley. When the Baxley feed was cut this morning, the whole system shut down because the primary transmitter (fed from Brunswick) was already in error mode, for reasons unknown to us. We powered the entire system down and it started transmitting on the primary Brunswick feed as it should have been."
The licensee notified the NRC resident inspector. Notified R2 DO (K. Barr).
