| Title | Agreement State Report - Level Gauge Stuck Shutter |
| Event Description | The following was received from the State of Illinois via email:
At approximately 1052 [CDT] on 9/7/17, the RSO for lngredion (IL-01065-02) reported a shutter stuck in the 'on' position for a level gauge at their licensed facility in Bedford Park. The inoperable condition of the shutter and the resulting removal of the gauge from service occurred on 9/6/17. Reportedly, due to the mounting location of the device, no potential for exposure to personnel existed. The gauge has been removed and locked out by SAHCI [Stan A Huber Consultants, Inc.]. No surfaces of the gauge exceed 2 mR/hour and appropriate action for disposal is pending. The licensee reports an electronic switching device operates the shutter. This automatic device was bent and deformed as part of the operating process and the rod portion of the shutter was cracked most of the way through. As part of the remediation process, the shutter push rod broke off completely. Several unsuccessful attempts were made using WD40 and a pin to close the shutter. The gauge was removed from operation by SAHCI, keeping the primary beam away from all personnel. A 2x4x4 inch lead brick was secured to the face of the gauge. The exposure rate at the face of the gauge was less than 2mR/hr at all accessible surfaces. The gauge was secured in the locked radioactive material storage cabinet. The storage cabinet has five nuclear gauges stored within. The outside of the storage cabinet is less than 2mR/hr at the surface. The current plan is to properly dispose of the stuck shutter gauge. [SAHCI] request a disposal quote. The SSDR indicates maximum exposure rates for this device (max 500 mCi Cs-137) when the shutter is in the 'ON' position are less than 50 mR/hr at 5 cm and less than 5 mR/hr at 30 cm. |
