RESPONSE TO VIO 56348 364/96-09-01 0
VIO 50-348,364/96-09-01, " Multiple Wive Misalignments By System Operators" states:
Technical Specific:aion (TS) 6.8.1.a requires that applicable written procedures recoramend in Appendix A of Regulatory Guide 1.33, Revision 2, dated Febmary 1978, snall be established, implemented, and maintained. Regulatory Guide 1.33, Appendix A, Sections 3.s(2)(a) and 3.n recommends procedures for startup, operation and shutdown of emergency power sources (e.g., diesel generators) and the Chemical and Volume Control System (including Letdown / Purification System).
Contrary to the above, non-licensed system operators (SO) in two separate events failed

i
{
to properly implement applicable system operating procedures (SOP) as written, resulting in mispositioned valves that adversely aff'ected operability of the IB emergency diesel generator (EDG) and initiated two plant transients.
i This is a Severity Level IV violation (Supplement I).
Adjpission or Denial l
The violation occurred as described in the Notice of Violation.
Reason for Violation i
The cause of the mispositioned valves was personnel error in that personnel did not give adequate attention to detail during performance of procedures.
As a result of these events and others which occurred since the events cited in the violation, a review was conducted to identify commonalties among the events. From the review of these events, it was concluded that a lack of attentiori to detail with regarda to procedural usage, I
procedural adherence and self checking resulted in the occurrence of the errors. Furthermore, the lack or the inadequacy of pre-job briefings contributed to these events.
l Corrective Steos Taken and Results Achieved The two valves were closed and a checklist performed for the DG Fuel Oil Transfer System to verify all valves in the system were positioned correctly.
The valves that were mispos;tioned during the fluffing of the mixed bed demineralizer were returned to the correct position.
i The two individuals involved in the events have been disciplined.

l RESPONSE TO VIO 50-348,364/96-09-01 j_
Following the second mispositioning event, a plant wide work stoppage was called to discuss this and several other similar events that had occurred since the outage had begun. Managers met with their groups and discussed these events and reemphasized the use of self-checking principles and procedural adherence.
A review of other recent events has revealed similar problems oflack of attention to detail and conununication problems which could have been mitigated or prevented by performance of a i
pre-job brief. A Training Advisory Notice has been issued to Operations personnel stating Operations Management expectations on pre-job briefing requirements.
l Corrective Steps That Will Be Taken to Avoid Further Violation These events will be reviewed with all Operations personnel. In the review, management expectations for pre-job briefing, self checking, procedural usage and adherence will be emphasized.
