| Title | Agreement State Report - Nuclear Gauge Stuck Open Shutter |
| Event Description | The following was received via email:
On August 21 the Agency [Illinois Emergency Management Agency] received a call from a representative of Clark Dietrich Building Systems (CDBS), Rochelle, IL (reg no 9223802) concerning findings made by their contractor for a generally licensed gauging device at their facility. A Gamma Instruments model GR100 device (s/n 930-706) with a 1000 milliCi Am-241 source was found to have a stuck [open] shutter during maintenance/operability checks being performed by a field engineer from Advanced Gauging Technologies. Repairs were made by the contractor and the gauge subsequently returned to service with no additional issues noted. The field engineer reported that apparently dirt and debris had accumulated from the rolling operations line in such a manner as to prevent proper closure. The caller from CDBS indicated that the gauge had just been last checked by their own staff on July 8, 2014 and no issues with the shutter were detected at that time. He went on to say that he expected a full report from the contractor to be provided in a few days and would forward that information when it became available. Until the full report from the registrant and the field engineer are received, this matter will remain open. However, based on the information provided at this time no on-site investigation is warranted. No personnel exposures resulted from this event. Illinois Incident Number: IL-14014 |
