AUTOMATIC REACTOR TRIP DUE TO TURBINE TRIP
"The Moisture Separator drain tanks each provide a trip signal to the main turbine on a high level on 2 [of] 3 level switches. At 0419 [EST], 2 [of] 3 level switches indicated a high level in the 3A Moisture Separator Drain Tank Level, resulting in a MT [Main Turbine] trip and anticipatory RPS trip. Post-trip response was normal."
All rods inserted into the core. No PORV's lifted. No ECCS actuation. The cause of the heater drain system upset is under investigation.
The licensee notified the NRC Resident Inspector.

OFFSITE NOTIFICATION DUE TO SIREN MALFUNCTION
"At 07:45 [CST] on 11/14/02, ANO Security received offsite calls from an off-duty security officer and the Pope County 911 Office regarding actuation of up to 3 emergency sirens in the Russellville area. The sirens silenced automatically approximately 3 minutes later after they timed out. Information provided by the duty Emergency Planner indicated the cause of the sirens was attributed to a power fluctuation in East Russellville area. The Arkansas Department of Health was contacted and is responding to determine if any corrective maintenance is required. The 911 Office is getting multiple calls from concerned citizens about the sirens. Local radio stations have been made aware of the event and are periodically broadcasting that there is nothing to worry about in an attempt to inform local residents."
Licensee notified the NRC Resident Inspector.

LOST I-125 SOURCE, SLIGHTLY < .5 MILLICURIES, TO BE IMPLANTED IN A PATIENT
Following prostate implantation procedure, radiograph showed fewer seeds than believed to have been implanted in the patient (1 seed short). Room, trash, and linens were all surveyed and nothing found. The authorized user believes that the lost seed may have migrated to another location in the patient's body, possibly carried off by one of the surrounding blood vessels.
X-ray and CT scans of the immediate area of the implantation did not reveal location of the lost seed. No further scans of the patient are planned.

ELECTRICAL AUXILIARY BUILDING SUPPLY FAN TRIP
"The Unit 2 Train C Electrical Auxiliary Building Supply Fan tripped on overload current shortly after starling on Nov 1 2002. The fan then tripped two more times on overload during subsequent troubleshooting. It was determined that the fan overloads for all 3 trains of EAB HVAC in both units were set low such that these fans may trip under reduced grid voltage conditions. All fan overloads were reset at a higher value to protect the motor and allow acceptable performance during the range of design grid voltage conditions.
"The design safety function of these fans is to ensure the environmental requirements of vital equipment are satisfied under analyzed conditions including transients and postulated accidents. Since this condition existed prior to correcting the fan overload setpoint value, it was determined to be a condition that could have prevented fulfillment of a safety function. Therefore, this condition is reportable under 10CFR50.72(b)(3)(v).
"This condition is susceptible during reduced grid voltage conditions. Further evaluation is in progress and expected to demonstrate that the reduced grid voltage condition occurs during a limited period of time over the operating cycle. Therefore, it is believed that the analysis will conclude that this event is of low safety significance."
The NRC Resident Inspector was notified of this event.
