Title	Fixed Process Gauge Failed Semi-Annual Shutter Test
Event Description	A Tracerco 600DP series nuclear gauge licensed to ENI US Operating Company failed a semi-annual shutter test on June 4, 2011. The gauge is located at Oliktok Production Pad, Oliktok Point, Alaska. Specifically, the RSO for the gauge stated that the extension rod (attached to the arming rod with the cesium source) could not be withdrawn sufficiently to move the source behind the shutter mechanism. Binding of the arming and/or extension rods could be felt in attempts to move the source behind the shutter mechanism. Mechanical restrictions were felt as the RSO successfully returned the source to its in-service position following the failed shutter test. The gauge is currently in-service and there is no immediate operational or safety requirement to lock this gauge out. Tracerco has been notified of the deficiency by phone. Tracerco will provide a technician to repair this discrepancy. The 600DP gauge houses a 925 MBq Cs-137 source with serial #RM510.
