| Title | Gauge Shutter Stuck Open |
| Event Description | On Sept 21, 2009, [the licensee discovered] a stuck shutter on an ammonia tank (top) in the catalyst area. The gauge is an Ohmart Model SH-F2, Serial 64692, containing 800 millicuries of Cesium-137. The gauge was originally installed in 2006. The stuck shutter was discovered during a routine 6 month shutter check on Sept 18, 2009. The technician tried to electrically close the shutter, but was unable to do so. [The licensee has] scheduled a service provider for repair within the week. The source is safely mounted on the side of a tank, [and the licensee] expects no exposure to occur. The Ohmart manufacturer was contacted.
An Ohmart service representative responded to the site to repair the gauge. It was determined that a fuse had blown in the gauge actuating circuit and that the shutter was not mechanically stuck. The gauge has been repaired and returned to service. R1DO (DeFrancisco) and FSME EO (McIntosh) have been notified. |
