Title	Agreement State Report Involving Stuck Shutter on Level Gauge
Event Description	On January 10, 2014, the Agency received a report from the licensee's Radiation Safety Officer (RSO) stating the shutter on a Ohmart Vega model SGLG gauge containing a 500 millicurie cesium - 137 source was found stuck in the open position. Open is the normal operation position of the gauge shutter. The RSO stated a contractor was performing a calibration of a level detector on January 9, 2014, when they could not get the gauge shutter to close. The contractor sprayed the shutter with a light oil and attempted to rotate the handle and operating arm. While trying to free the shutter, the operating arm separated from the gauge. The contractor was able to insert the operating rod into the gauge, but the shutter would not move. The manufacturer has been contacted to assist in the repair or replacement of the gauge. No exposure resulted from this event and the current position of the gauge shutter does not create any additional exposure risk to any personnel. A contact dose rate survey of the gauge was conducted and the highest reading observed was 1.2 millirem per hour. Additional information will be provided as it is received in accordance with SA-300. Texas Incident Number: I-9145
