| Event Text DETECTABLE CESIUM CONTAMINATION FOUND IN SOURCE SAFE DRAWER
A contractor removed cesium sources from a source safe located in a storage area. The sources were removed, packaged, shipped without incident. Surveys were conducted in the safe, and the survey in the lower safe drawer revealed contamination levels greater than 5000 dpm per 100 square centimeters. The lower drawer of the safe has not been used during this recent storage and transfer of sources. The licensee reported to the state that they believed it was "legacy" contamination. Individuals involved in the source transfer were surveyed. No contamination was found. The storage area and passageway to and from the storage area were surveyed. No contamination was found. The licensee has secured the safe and the contaminated area. The area is secured and posted with "no access" signs. The state will follow up with their licensee once a decontamination service completes the decontamination of the affected areas and is ready to release the area for general use.
The state notified Region 3 (Jim Lynch). |

| Event Text CRITICALITY WARNING SYSTEM DISABLED
"At approximately 0600 on 12/16/2008, the horns of the inside Criticality Warning System (CWS) covering the Fuel Manufacturing Operation (FMO) were discovered to be in manual mode. On 12/12/08 at approximately 0700, the horns had been taken out of automatic mode and placed in manual mode as part of system maintenance activities at 0700 and inadvertently remained in this condition until this morning at 0600. According to a preliminary investigation, it appears that following maintenance on 12/12/08, incomplete system restoration left the automatic horn function disabled but the detection system remained operational.
"Once identified, the system was immediately restored to the automatic mode and the inside FMO CWS system was returned to normal operation. Follow-up tests have confirmed that the warning system horns are fully operational.
"The event is being reported within 24-hours pursuant to 10CFR70.50(b)(2) as an event in which safety equipment was disabled."
During the time that the warning system was disabled, there were no conditions that would have resulted in warning system activation. Corrective actions have been taken to prevent re-occurrence. The licensee will be notifying NRC Region 2 as well as State and local governments. | |
