| Title | Agreement State Report - Level Gauge Shutter Malfunction |
| Event Description | On 8/29/08, Incident Investigation Program received a letter from the licensee stating that on June 23, 2008 while conducting their routine surveillance, a Ohmart/VEGA level gauge used on their vent stack for level detection failed the inspection when the shutter mechanism failed to close fully. An inspection of the gauge found that a bolt on the operating handle had sheared and the shutter would not close. The gauge contains one 200 millicurie Cesium (Cs) - 137 source serial # M-7089. The licensee has contacted the manufacturer and is working with them to schedule the repair of the gauge. Surveys conducted by the licensee has determined that dose rates in the area of the gauge are normal and do not pose a risk of exposures to their workers. The source has been labeled 'Do Not Operate - Contact Site RSO'.
This event is also identified as Texas event number I-8546. |
