ENS 4180228 June 2005 08:20:00Following troubleshooting to remedy density measurement problems, the Cs-137 source (100 milliCuries) and source holder were found missing from its liquid line gauge mounting. It was then determined that the source and holder had become separated from the gauge and had fallen into a sump directly beneath. The gauge is a Ronan Model SA-1-C5, S/N EE823. The licensee isolated the area and performed surveys with no contamination or abnormal radiation readings noted. The licensee contacted the manufacturer and subsequently contracted with a consultant (Jendco, Inc. of Pittsburg, PA) who retrieved the source and source holder from the sump without incident. The source was found intact and undamaged. The gauge was re-assembled and returned to service.
