AGREEMENT STATE REPORT - TRITIUM EXIT SIGNS LOST IN SHIPMENT
The following information was received via facsimile (North Carolina Incident report 04-19):
"The shipment was picked up from SRB Technologies, Inc. in Winston Salem, NC. The shipment was to be delivered to Wild Sales Co. in Santa Fe Springs, CA by Pilot Air Freight (shipment #070743258). Pilot Air Freight picked up a shipment of 14 boxes of which 13 boxes contained 129 tritium exit signs from the licensee on April 23, 2004. The balance of 1 box contained sign accessories/hardware. The sign customer notified the licensee that a box was missing on April 28, 2004. Pilot freight was immediately informed and they began investigating. Final confirmation was given to the licensee on May 11, 2004 that the box could not be located. The missing box contained 10 exit signs each containing 9.9 curies of tritium. The serial numbers of the missing signs are 316493-316502."

LOSS OF EMERGENCY ASSESSMENT CAPABILITY DUE TO LOSS OF NORMAL POWER TO TSC
The following information was obtained from the licensee via facsimile:
"A loss of emergency assessment capability occurred due to a loss of normal power to the Cooper Nuclear Station Technical Support Center [TSC]. At 1055 [CDT], power loss occurred due to a ground fault on the feeder to the motor control center [supplying] power to the TSC. Power was transferred to the alternate feeder for the TSC at 1214 [hrs]. Alternate power was available during the entire time, however due to the nature of the ground fault, transfer was not performed until source of ground was known: (during 'bump' checking of a chiller compressor, the compressor internally shorted causing the ground fault protection circuitry to activate for the feeder breaker [Electrical Panel designated OBFP].) The source of fault has been identified and has been isolated.
"Normal power was restored to the TSC at 1443.
"The emergency offsite facility and the main control room were unaffected by the ground fault.
"The NRC Senior Resident Inspector has been notified of this event."
No other safety systems were affected by the loss of the feeder circuit. Prior to finding the fault, the system was undergoing maintenance. The 'bump' check involves momentarily powering the chiller compressor to verify proper and free rotation.
