The following information was received fro … The following information was received from the State of Nebraska via facsimile:</br>The licensee uses fixed industrial gauges for measuring densities in fly ash hoppers at the station's precipitator building. The industrial gauges contain a Cesium 137 sealed source. The Cesium 137 sources were originally installed in 1975 and at the time contained 50 millicuries per source. </br>The sources were manufactured and installed by Kay Ray Inc.</br>The gauges are Model No. 7700-50.</br>The licensee was attempting to close the shutter on the fixed gauge prior to performing maintenance. One of the external closure cables was found to be slightly bound up and only partially closed the 'internal' source shutter. The cable closure was reopened, which reopened the source shutter up at the sealed source. Closure was tried again. This time the cable, which connects the handle at the floor to the sealed source shutter mechanism 20 feet above, bent instead of sliding the cable to the closed position. </br>This 'event' happened at 11:35 am and was reported to the station's Shift Supervisor who in turn contacted the plant electricians to make repairs so the precipitator 'tag-out' could continue. By 11:45 am the cable had been closed and the lab contacted to perform a survey to verify the source shutter was now in the closed position. No personnel were exposed to radiation during this event.re exposed to radiation during this event. +
