Title	Agreement State - Stuck Open Gauge
Event Description	The following information was provided by the Illinois Emergency Management Agency (the Agency) via email: On September 11, 2024, the Agency was contacted by a representative for the Exxon Mobile refinery in Channahon to advise of a fixed gauge containing 20 mCi of Cs-137 [sealed source] had a reportable equipment failure. Specifically, on September 10, 2024, during routine shutter checks, the handle that operates the shutter broke off, leaving the gauge in the open position. The gauge is mounted to a production vessel which is full of commodity. There were no exposures, and due to the vessel being in use, personnel exposure is not a concern. The manufacturer has been contacted for repairs. The licensee met the notification requirements. This report will be updated with the source serial number and verification of repair and replacement upon receipt. Illinois Event Item Number: IL240021
