Title	Agreement State Report - Stuck Source
Event Description	The following was received from the State of North Dakota via email: American Crystal Sugar Company experienced a stuck sealed source (Berthold Technologies U.S.A., LLC Model SSC-100, 60 milliCuries [Co-60] at calibration) in a source tube located inside a vessel during a routine shutter check at their Hillsboro, ND location. The sealed source is fixed to a cable which allows the source to be lowered through a source tube which is located inside a vessel. Upon attempting to retract the source into the shielded gauge housing (Berthold Technologies U.S.A., LLC Model LB 8120-01) to perform the shutter check, the source did not budge. The licensee contacted Berthold Technologies U.S.A., LLC (manufacturer) regarding the stuck source. Berthold personnel instructed the licensee to apply a penetrating oil to the source tube in an attempt to break it loose. As of the notification time, the source remained lodged in the source tube in its normal operating position. The five detectors associated with this source continue to read radiation levels as expected. The licensee will continue to apply the penetrating oil and attempt to pull it back into the shielded gauge housing and provide an update in the morning. More information will be provided as received. ND Incident Report # ND180001
