The following report was received from the
Tennessee Department of Environment and Conservation Division of Radiological Health via email:
The licensee called to report a radioactive material gauge with stuck source in the closed position. The gauge is a Vega Model SHLM-C2, with three 37 millicurie Cs-137 rod sources, SNs 2609, 2611, and 2612. Radiation measurements indicated the source was in the shielded position. On March 9, 2015, a Vega service representative visited the site and inspected the gauge. It was discovered the source was not completely retracted. The gauge remains bolted to the process vessel, and is scheduled for replacement after additional retraction or equivalent means to secure the source has been implemented. No additional radiation exposure to personnel occurred. Current radiation levels are the same as found under normal conditions when the source is in the retracted position.
