Title	Process Gauge Stuck Shutter
Event Description	The following is a synopsis of an event received via email: On April 11, 2019, a trained technician was in the process of performing the biannual inventory/shutter check when the individual reported that Kay Ray Model #7050, Serial #1399, 250 mCi, Cs-137 gauge located on 5B DTU (Deslime Thickener U/Flow) in the Deslime basement had a frozen shutter mechanism and cannot be closed, rendering the shutter non-operable. The gauge won't be replaced until the first time the slurry pipeline goes down for repair. If the line goes down prior to that, the gauge will be replaced at that time. Similar events in the past have never had an exposure to any individuals. In the event of an emergency, the gauge will be removed and placed on a piece of lead and brought to storage.
