BURNT SMELL FROM HIGH PRESSURE COOLANT INJECTION (HPCI) STEAM SUPPLY VALVE BREAKER. HPCI DECLARED INOPERABLE AND 14 DAY LIMITING CONDITION OF OPERATION ENTERED PER TECHNICAL SPECIFICATION.
An undervoltage alarm was received in control room from HPCI Direct Current Motor Control Center (DCMCC) D312 which is located in the HPCI room. An operator was immediately dispatched to investigate the undervoltage condition on D312. The operator discovered that HPCI Steam Supply Valve, ( MOV-2036), breaker, (D31206), had a burnt smell. The breaker was opened and HPCI Steam Supply Inboard Isolation Valve was closed. HPCI was declared inoperable and a 14 day Limiting Condition of Operation was entered per their Technical Specification. Emergency Core Cooling Systems and Reactor Core Isolation Cooling are fully operable if needed. Their was no fire and the licensee is investigating.
The NRC Resident Inspector will be notified of this event by the licensee.

"This notification retracts a notification made 4/14/00 for HPCI being declared inoperable due to a suspected electrical problem in a DC motor control center (MCC). An undervoltage alarm was received, and a burnt smell near the MCC was observed. The HPCI system was isolated per procedure. Investigation revealed a low voltage monitoring coil had failed The coil was replaced and successfully tested. The system was returned to its normal standby condition.
"This coil performs a monitoring function only. Failure of the coil, or any effects of the failure would not have prevented the MCC or HPCI system from performing their required safety function. The HPCI system was fully operable until removed from service to investigate the condition and replace the coil."
The NRC resident inspector has been informed of this retraction. Notified R3DO (Ring).

SOURCE DISCONNECT ON CAMERA OWNED BY INTERNATIONAL RADIOGRAPHY & INSPECTION SERVICES INC.
A radiography camera being used for an inspection by International Radiography & Inspection Services Inc. at the Matrix Fabrication Division site in Catoosa, Ok. had a source disconnect while being cranked out. The source, which contained 72 curies of Iridium-192, was manufactured by AEA Technologies and mounted in a SPEC camera. During the time of the source disconnect, the area around the camera was secured. The licensee RSO went to the site, did a source recovery and returned the camera to their facility. There were no exposures >40 mrem. The licensee has packaged the equipment and will FedEx it to AEA Technologies for their analysis of the problem.
