Title	Agreement State - Fixed Process Gauge Failed Shutter Check
Event Description	The following report was received from the State of Illinois via e-mail. While performing routine shutter checks of fixed gauges at the licensee's site, a device failed to perform as expected. As a result, the Radiation Safety Officer contacted the Agency and made the required report. The failed Ohmart/Vega Model SH-F2 gauge is used for level detection on a high temperature, high pressure vessel. The vessel is located on a roof 50 feet above grade with the nearest workstation approximately 300 feet away. The gauge was left in the 'on' position so as to allow continued routine operation of the process line. Shift supervisors and site personnel were advised of the situation and any entry into the vessel has been prohibited should the line become disabled or shut down. The manufacturer has been contacted and arrangements are pending for repair of the device at the first available opportunity. Should the gauge mounting fail and it become necessary, additional shielding material is available on-site to cover the open beam port and personnel have adequate training to perform that task. No threat to health and safety exist at this time and there are no associated exposures. The Ohmart Gauge Model SH-F2, Serial Number 7306GK contains an 0.3 Ci sealed Cs-137 source. Illinois Report Number IL11120
