• Cause Description Continued From Line 10 instrument was recalib~ated and an evaluation was performed of the consequenQS of this error assuming that it had existed over the previous five months. While this evaluation was in progress,' the C SI bottle level was found to be 60%

(1.6 percent above the Technical Specifications limit) at 0015 on 6/8/77. The level was returned to .within specifications by 0100 the same morning. Meanwhile, the concurrent investigation revealed that numerous violations from 1 to 2 percent below the Technical Specifications limit had occurred for C bottle under the above assumption. The discrepancy developed due to conflicts between the bottle level indicators and high-low level switch alarms, Probable Consequences From Line 15 Since the violations described above are of such similar nature, they are being treated in a single event report. It should be noted that since the violations occurred for only one of the four SI bottles and that the other three had normal levels, the total volume available in each instance for a safety injection was certainly within acceptable limits *
