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.
