Smith Dated April 6, 1979 USNRC INSPECTION 70-820/79-04 USNRC COMMENT Contrary to the requirements of 10CFR70.24 (a) (2), on February 12, 1979, three monitoring devices in the criticality monitoring system had a preset alarm point of 30 millirem per hour (10CFR limit is 20 millirem per hour).
UNC RESPONSE The alarms in question were immediately reset to the proper set point when the condition was discovered.
The NIS technician who set these alarms was aware of the correct numerical setting.
However, he was not experienced in working with log scales, and as a result, misread the scale.
The technician who made the error was promptly reinstracted on the proper reading and setting of these meters.
In addition, a review was made of other aspects of his work to determine if any other such problems existed.
None were found.
Finally, the importance of adequate training and training overchecks was stressed with all personnel who were involved in the training of this individual.
