Title	Agreement State Report - Fixed Nuclear Gauge Found with Stuck Shutter
Event Description	The following information was received from the State of Illinois via email: On Tuesday afternoon, the Agency [Illinois Emergency Management Agency] received a call from the RSO for Flint Hills Resources Chemical Intermediates, LLC (IL-01337-01). He called to report a shutter failure of a fixed gauge which he cannot close. The device manufacturer, Ronan Engineering, has been contacted and arrangements are pending for repair of the device. The RSO has isolated the area, posted warning signs and instituted a lock out/tag out procedure for the manway entrance to the vessel in order to prevent exposures which might occur from someone attempting to perform work within the tank that the gauge is located. Area surveys performed show no variations above normal (i.e., less than 1 milliR/h at 1 foot) for when the shutter is open and the unit is in operation. The shutter had last been tested in March with no abnormalities noted. The gauge has not been subjected to any corrosives or solvents or other conditions which exceed the gauge's prototype test conditions. The RSO was reminded of the requirement to provide a written report within 30 days of the event and to contact the Agency when the manufacturer was able to perform the site visit to evaluate/repair the device. The Agency considers this matter open pending those additional actions. The Ronan gauge is model X90-SA1, S/N M7389, contains 24.5 mCi Cs-137.
