Alert

Due to a lapse in appropriations, the NRC has ceased normal operations. However, excepted and exempted activities necessary to maintain critical health and safety functions—as well as essential progress on designated critical activities, including those specified in Executive Order 14300—will continue, consistent with the OMB-Approved NRC Lapse Plan.

AGREEMENT STATE REPORT - FLORIDA - STOLEN MOISTURE DENSITY GAUGE.

A truck belonging to the licensee flipped over on a highway in Polk County, FL on January 1, 2007, at approximately 8 or 9 pm. The truck was carrying a Humboldt Model 5001EZ moisture density gauge (nominal 50 millicuries Am-241/Be and 10 millicuries Cs-137). The driver was unhurt and walked to a local business to report the accident leaving the gauge unattended. The gauge was stolen while the driver was gone. Police were notified and a report filed. The gauge was locked inside of the locked case and chained to the vehicle.

FL report #FL07-001

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.

HIGH RANGE EFFLUENT RADIATION MONITORS DECLARED INOPERABLE DUE TO COMMON CAUSE FAILURE

"At 17:43 CST Cooper Nuclear Station declared the three High Range Kaman Effluent radiation monitors inoperable due to a common cause failure mechanism. The affected Kamans monitor the Elevated Release Point exhaust, the Turbine Building ventilation exhaust and the Radwaste/ Augmented Radwaste Building ventilation exhaust during accident conditions. The identified common failure mechanism results in the installed, movable calibration sources spuriously inserting into the monitors, causing them to indicted abnormally high.

"This condition is being reported under 50.72 as a loss of Emergency Preparedness Capabilities due to the potentially inaccurate indications of the High Range Building Exhaust radiation monitors and the Elevated Release Point Effluent radiation monitor."

The NRC Resident Inspector was notified of this event by the licensee.
