Title	Agreement State Report - Nuclear Gauge Shutter Found Stuck
Event Description	The following information was received from the State of Texas via email: On July 8, 2015, the Agency was notified by the licensee's radiation safety officer (RSO) of a stuck shutter on an Ohmart Vega SH-F2 nuclear gauge containing a 500 millicurie Cesium - 137 source. The stuck shutter was found during a routine six month inspection. The RSO determined the source shutter would not operate due to internal corrosion seizing it in the open position. The RSO verified the radiation levels in the area of the gauge had not changed. The RSO stated the source normally operates in the open position and there are no safety issues. The RSO stated he had contacted a service provider to make repairs to the gauge. The RSO stated a replacement internal shutter mechanism equipped with a gasket will also be ordered for installation to prevent future water intrusion and corrosion. The gauge does not pose an exposure risk to the licensee's workers or to members of the general public. Additional information will be provided as it is received in accordance with SA-300.
