AGREEMENT STATE REPORT - FAILURE OF FIXED GAUGE SHUTTER MECHANISMS TO CLOSE
The following excerpted information was received via e-mail:
During shutter checks performed by the licensee, it was discovered that four of their fixed gauge shutter mechanisms were unable to be closed. The following is information on those gauges: (1) Berthold, Model LB-7440-D, source SN FR288, Cs-137, 30 mCi; (2) Berthold, Model LB-300-L, source SN 1080/1-05-98, Co-60, 1.16 mCi; (3) Berthold Model LB-7440-D, source SN 1080/2-05-98, Co-60, 1.65 mCi; and (4) Berthold, Model LB-7442-D, source SN 2572-8-90, Cs-137, 250 mCi. On gauge 1 the shutter handle broke off. On gauges 2, 3, and 4 the shutter stuck open. The licensee has requested service from the gauge manufacturer.
Mississippi Incident Number: MS-10002.

TECHNICAL SUPPORT CENTER EMERGENCY VENTILATION SYSTEM MAINTENANCE
"On Thursday, February 11, 2010, the Limerick Technical Support Center (TSC) emergency ventilation system will be removed from service for planned preventative maintenance activities on the damper flow controller and air filtration charcoal system. During the maintenance, the non-emergency ventilation system will be functional. The TSC air filtration fan and dampers will be non-functional, rendering the TSC HVAC accident mode non-functional. This maintenance is scheduled to minimize out of service time. The planned TSC ventilation outage is scheduled to be completed within 12 hours. If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing EP [Emergency Planning] procedures and checklists. If radiological conditions require TSC facility evacuation during ventilation system restoration, the Station Emergency Director will evacuate and relocate the TSC staff in accordance with applicable site procedures."
The licensee has notified the NRC Resident Inspector.

The maintenance on the Limerick Technical Support Center (TSC) emergency ventilation system has been completed and the TSC is available.
The licensee has notified the NRC Resident Inspector. Notified R1DO (Powell)

AGREEMENT STATE REPORT - DAMAGED NUCLEAR DENSITY GAUGE
The following report was received via e-mail:
"At 1310 [PST] on February 11, 2010, the C.Y. Geotech Radiation Safety Officer [RSO] reported that one of the nuclear density gauges (CPN, MC-1DRP, MD90905316 containing 10 milliCurie of Cesium 137 and 50 milliCurie of Americium-241:Be) had been run over by a truck at a construction site. Los Angeles County Radiation Management responded to the scene and found that although the source rod was broken and the plastic case was broken into pieces, the Cesium 137 and the Americium-241:Be sources were still in the shielded body of the device and were intact. There was no contamination. The highest dose rate on the body of the device housing the sources was 9 mR/hr and at one foot was 0.9 mR/hr. The gauge was placed into 2 plastic bags and was placed into the transportation case. The licensee will deliver the gauge to Maurer Technical Services (a licensed CPN representative) who will then ship the gauge to CPN for disposal. [The RSO] reported the gauge user walked about 10 feet away from the gauge to report his test results to a job supervisor and this is when the gauge was run over. The RHB-Brea office will cite the licensee for failure to maintain adequate control over the gauge. The licensee has been instructed they need to provide [California Radiation Control Program] with a report within 30 days as required by regulation. The licensee states they will retrain all of the gauge users regarding the control of the gauge to avoid a similar incident in the future.
