The following information was received from the Commonwealth of Virginia:
The licensee discovered a shutter stuck in the open position during a routine test of a fixed gauge on May 5, 2014. The gauge is a Ronan Engineering Model SA1, serial number M-7299. It is used as a low-level indicator in a pre-dryer vessel and contains a 26.9 milliCurie (decay corrected) cesium-137 source. The licensee indicated that using unusual force to try to close the shutter would likely damage the actuator rod mechanism. The shutter is kept in the open position during operations and does not pose an additional radiation exposure to personnel. The licensee performs radiation surveys at one foot from the gauge surface during routine tests. The maximum reported result for this gauge was 300 microR per hour. The licensee has contacted the manufacturer to repair the gauge. The Agency [Virginia Radioactive Materials Program] will continue to monitor the situation until the shutter is repaired.
