FLORIIA TOER GRTOPATIQi RESPONSE Florida Pwer Corporation (IK) accepts the violation.

APPARDTP CAUSE OF,YlQI.ATICU

1) Failure to cartply with the the procedural requirements of MP-lbo is a cambination of failure to follow sucodure ard procedural inadequacy.

Step 4.2.5 calls for QC to verify the conditicn of all machired matirg surfaces. Failure to list what mating surfaces were intended by "all macitined mating surfaces" did not provide adoquate guidance for the craft performing the work activity nor did it provide adequate placement of QC hold points. 'Ibe Quality control Inspector advisod the maintenance personnel that there were additional inepections to perforn prior to r==dly, but this information was not cxrtrunicated to the next maintenance shift and there were no reminders referrirg workers back to step 4.2.5 in the prvcidure.

2) 'Ibe cause of the violation is attributed to personnel error. On several occasions ASV-167 was unlocked and repositioned to adjust bypass steam ficw. Ib11 cuing one of the adjustmonts, the personnel L irreolved failed to re-1cx.k the valve.
