| Title | Gauge Shutter Operated Slowly in the Close Direction |
| Event Description | On December 18-19, 2014, Operations personnel detected a local indicating light showing the gauge shutter in the open position. Control room indication and local area surveys indicated the gauge shutter was closed. During the annual Christmas maintenance shutdown, a gauge contractor was onsite and the licensee requested that the suspect gauge shutter be investigated. On January 3, 2015, the gauge technician changed sensors for shutter open/close indication noticed slow operation of the shutter in the close direction. The technician made adjustments to the gauge shutter so that it would slide freely. The technician also recommended routine lubrication to prevent this issue in the future.
The gauge contains 300 mCi Sr-90 source. Gauge serial number 3737622, Source serial number S432-A. No adverse personnel exposures are expected as a result of this event. |
