Title	Agreement State Report - Fixed Gauge Shutter Failure
Event Description	The Commonwealth of Virginia submitted the following report via facsimile: On June 14, 2012 the licensee reported that the shutter of one of its fixed gauges could not be closed as designed. The gauge is a Ronan Model SA-1 used on a process vessel as a level indicator. It contains a 438 millicurie (decay corrected) cesium-137 source. The problem was discovered during a routine test of the shutter mechanism. The individual who performed the test indicated that forcing the shutter closed, if possible, could damage the control mechanism. The gauge is normally in the open position during operations and the licensee has take extra steps to ensure no entry into the vessel. Ronan Engineering Company, the gauge manufacturer, has been contacted by the licensee and has scheduled a site visit during the week of June 18, 2012. VA Event Report ID: VA-12-002 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.
