Title	Agreement State Report - Stuck Closed Shutter on Fixed Radioactive Gauge
Event Description	The following information was obtained from the State of Illinois via email: On October 4, [2016], the licensee's radiation safety officer contacted the Agency [Illinois Emergency Management Agency] to report a defective fixed gauge. While performing routine operational checks of fixed gauges at the site, the shutter on a device appears to have become disconnected from its handle and will not operate properly. It was determined from radiation measurements that the shutter is currently in the 'closed' position. Radiation levels are less than 2 mR/h surrounding the device and it is in an area that is routinely inaccessible. The gauge is mounted on a reaction process vessel and is subject to the ambient weather conditions with no prior operational issues for 27 years until now. Arrangements are pending with a manufacturer's representative to investigate the matter and repair/replace the device. Source/Radioactive Material: SEALED SOURCE GAUGE Radionuclide: Cs-137, 0.064 Ci, 2.368 GBq Manufacturer: VEGA AMERICAS, INC. Model Number: A-2102 Serial Number: M3107 IAEA Category: 4 Illinois Report No.: IL16009
