Title	Agreement State Report - Stuck Shutter
Event Description	The following was received by the State of Illinois via email: The Radiation Safety Officer (RSO) at Equistar Chemical notified the Agency [Illinois Emergency Management Agency] via email that while performing routine shutter tests of fixed gauges at their Morris, IL location, it became known that for one of the gauges, a shutter was stuck in the 'open' position. The affected Ohmart Vega model SH-F2 gauge contains 300 milliCi of Cs-137 and is mounted on a reactor vessel within a secure area at the plant. The associated process line for the vessel does not have any maintenance scheduled to occur until next year, therefore, no entry into the vessel should be necessary and the gauge is expected to remain in the 'on' position due to operational need. The gauge manufacturer has been contacted and advised of the situation. Equistar and Vega Americans are currently attempting to schedule a field service engineer to come on site to investigate the matter and make necessary repairs/replacement. The licensee has previous experience with events of this type due to the large number of devices in use and the stressful environment that exists at this site. The licensee is prepared to respond to any further deterioration that, although not likely, may occur. Plant personnel have been advised of the matter and the process line supervisors have been instructed to contact the RSO should any abnormal events associated with the reactor processes becomes known. No on-site investigation is planned by the Agency at this time. Illinois Item Number: IL16008
