| Title | Agreement State Report - Level Gauge Cesium-137 Source Would Not Retract |
| Event Description | The following information was provided via email:
On April 9, 2009, at 19:21 the Agency [state] received a phone call from the Radiation Safety Officer (RSO) at Flint Hills Resources in Odessa Texas. The RSO reported that a 300 millicurie (120 mCi calculated) Cesium (Cs) -137 source used in an Ohmart\VEGA model # SHLM level gauge would not fully retract into the source holder. The gauge is installed on the side of a [chemical] reactor vessel. The source will retract to the sleeve between the vessel and the gauge housing, but will not go into the gauge. The source is currently fully inserted into the vessel. Dose rates in the area are normal. No additional exposure was received by individuals at the facility. Management will meet on April 10, 2009, to determine how to address the source retrieval. The gauge was to be removed from the vessel for disposal by the manufacturer. The licensee will provide additional information next week. A similar event occurred at this facility in October, 2008 (EN44543). |
