STOLEN TROXLER MOISTURE DENSITY GAUGE
The following information was received via fax:
"On Friday evening we received a call from the [after-hour phone] service with instructions to call the SOC concerning a lost nuclear gauge. There were instructions to call [the] RSO for Pre-Test Lab [TXRAML02524] a licensee based in Georgetown, TX with authorization to possess and use a variety of moisture/density (M/D) gauges. The RSO explained that around 1500 hrs on Friday, March 10, 2006, one of his trucks was proceeding to a convenience store in the vicinity of Red Bud and County Road 122 in Round Rock, TX when upon arriving at the store it was noticed that the M/D gauge was missing. He admitted that the tailgate may not have been secured and the shipping container was not chained to the bed of the truck. An extensive search of the area traveled was conducted by Pre-Test as well as Round Rock PD and FD without finding the container. The device is a Troxler Model 3411-B serial number (S/N) 10260 with a 9mCi [milliCurie], Cs-137 source model TEL Dwg. #102112 , S/N 40-7662 and a 44mCi, Am-241source model TEL Dwg. #102451, S/N 46-1663."
Texas Incident No.: I-8312
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

FAILURE OF EMERGENCY EXHAUST SYSTEM DAMPERS
"At 1050 CST on 3/09/2006 the Auxiliary Building ventilation isolation damper, GKD0129, failed a preventive maintenance stroke test as the result of dirt buildup on the damper vanes. The associated Technical Specification action statement, T/S 3.7.13.a, was entered. At 0500 CST on 3/10/2006 mechanical maintenance personnel observed a similar buildup condition on the redundant train damper, GKD0128, which is in series with GKD0129. At 0838 CST on 3/10/2006 approval was given by the Shift Manager to stroke closed GKD0128 to verify Operability. At 0951 CST 3/10/2006 mechanical maintenance personnel observed that GKD0128 damper vanes remained approximately 45 percent open. T/S 3.7.13.b action for two inoperable emergency exhaust system trains inoperable due to inoperable auxiliary building boundary was entered and back dated to 0500 CST 3/10/2006.
"Having both trains of auxiliary building ventilation isolation dampers inoperable could prevent the ability to maintain the pressure boundary necessary to control the release of radioactive material.
"The licensee will notify the Resident Inspector."
