MEETING SUMMARY
I
j
This refers to the meeting conducted at the NRC's request in the Region IV
'
office on August 19, 1993. This meeting was related to the results of the
l
special inspection documented in NRC Inspection Report 50-285/93-12.
,
The attendance at the meeting is provided as Attachment 1.
The licensee
presentation is provided as Attachment 2.
During this meeting, the licensee discussed the circumstances, causes, and
corrective actions that would be taken to prevent recurrence of the failure to
properly control work activities in the switchyard and the failure to properly
install danger tags on plant equipment that were discussed in the special
inspection report.
Based on the results of this meeting, it appeared that the licensee had
established actions that appropriately addressed the events.
Sincerely,

JUNE 24.1993 PLANT TRIP
Root Cause
Failure of a Senior Relay Specialist to bypass or isolate a
.
critical / sensitive component prior to performing maintenance.
.
Contributing Causes
1)
Sticky AR relay door latch
2)
Inadequate understanding of NOD-QP-36
requirements
3)
Inadequate communications
4)
Lack of a formal decision making process for
determining online vs. outage work
Event Significance
Nuclear safety was maintained throughout the event. Of primary
significance was the breakdown in communications and control of
Switchyard work for an activity that was procedurally controlled.
