| Title | Fixed Gauge Shutter Sticking When Moved |
| Event Description | At approximately 1500 EST on December 29, 2014, an operator attempted to open the shutter on a fixed gauge Vega America source holder and determined that the shutter was sticking. The shutter was locked in the closed position and tagged out. The licensee performed a radiation survey and confirmed that the shutter was in the closed position. The licensee previously reported a stuck shutter on a nearby device (EN 50667). The licensee will contact the vendor to repair both devices.
Fixed gauge: Vega America Source Holder Model SHF 2-B with Cs-137 800 millicurie source. |
