"Security notified Limestone County Sheriffs dispatch at 0340 CDT that Browns Ferry had experienced a fire and arc-over event at the area of cooling tower switchgear 'C'.
"At about 0225 CDT a fault occurred in the cable tray between the 161 kV supply transformer and the 4 kV cooling tower 'C' switchgear resulting in clearing of the 161 kV line and a subsequent fire. The fire was extinguished at 0236 CDT by on-site responders. At 0340 CDT, Limestone County Sheriff department was contacted by site security and informed of the event and asked to increase patrols in the area of the county road adjacent to Browns Ferry. It was known that the event was likely due to operational issues and not sabotage but the final determination had not been made at that time. Limestone County Sheriff was contacted again at 0520 CDT and informed that the problem was operational and that their assistance is not required.
"There are no safety related plant equipment reportability issues resulting from this event. The reportability is solely due to notification of an outside agency.
"This condition is reportable within 4 hours according to 10 CFR 50.72(b)(2)(xi). Any event or situation, related to the health and safety of the public or onsite personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. Such an event may include an onsite fatality or inadvertent release of radioactive contaminated materials."
