Title	Stuck Open Shutter
Event Description	The following information was provided by the Illinois Emergency Management Agency (the Agency) via phone and email: The Agency was contacted on 12/10/2024 by representatives for Equistar Chemicals, LP (IL-01737-01) in Morris, IL, to report a fixed gauge shutter stuck in the open position [that was discovered on 12/9/2024]. The gauge is installed on the side of a process vessel and is normally in the open position. The shutter will remain in its normally open position and there will be no vessel entry. There are no changes in radiation levels except [expected levels resulting from] not being able to close the shutter. Entry to [the vessel] requires complete shutdown of the process line, and none are currently scheduled. The manufacturer's representative is on site today, 12/10/2024, to troubleshoot and make appropriate repairs. There are no exposures reported or anticipated as a result of this issue. Agency inspectors are coordinating a site visit to determine the root cause and corrective action. The licensee has provided a preliminary assessment that moisture can enter the housing and cause corrosion in the shutter. This report will be updated when additional information is available.
