| Event Description | The following was received via e-mail:
Licensee's RSO notified DRH [state] by phone on 3-22-11, and by letter received on 3-22-11, of a dislodged source from an Ohmart Vega Model SHLM-BR, fixed gauge Ser. No. 13530993. The source became dislodged from the main rod during the gauge's shutter test and fell into the gauge well. The licensee's surveys around the gauge well were less than 0.5 mR/hr. A gauge representative has been called in to repair the gauge. DRH [state] requested licensee send in manufacturer's service report with the licensee's written 30-day report. The source is 40 millicurie Cs-137, ser. No. 6965GK. Mississippi Incident Number MS-11004.
Licensee was contacted [by the state] on 4/7/11, for further clarification of the location of the source. The licensee's RSO said the source was at the bottom of the well inside a vessel. This would also be the case during normal operations. Surveys were also confirmed by the RSO to be 0.5 mR/hr around the vessel. Licensee's RSO said a new well is being built for the vessel and a service representative has been notified. Source retrieval and replacement of the gauge is scheduled for the middle of April once the new well is built, and the material in the vessel has cooled. Notified R4DO(O'Keefe) and FSME(McIntosh)
The following information was received via e-mail: Licensee submitted a field service report from the gauge service company on 6/9/2011. The service report indicated the roll pin in the rod was sheared and the source carrier fell to the bottom of the well. The service report claimed the roll pin was corroded due to the harsh environment that the source was in. Part of the rod was still attached to the source which was retrieved and inserted back into the source holder. The source was replaced, and the old source has been transferred. Notified the R4DO (Werner) and FSME (Persinko). |
