Vogtle Electric Generating Plant - Unit 2 USNRC Inspection Report 50-425/87-36 The Georgia Power Company wishes to submit the following information concerning the violation identified in the referenced inspection report.
Violation 50-425/87-36-01, " Failure to Follow Procedures for Quality Control (QC) Inspection of Mechanical Equipment" - Severity Level IV The Georgia Power Company (GPC) acknowledges the violation as identified in the USNRC inspection report.
Pullman Power Products (PPP) procedure IX-48,
" Equipment Installation," was revised in April 1987 to require the Equipment Field Engineer to verify and document acceptance for certain attributes previously inspected by QC.
The violation resulted when the PPP Equipment Field Engineer mistakenly thought the revised procedere allowed him to sign-off the process sheet for verification of a pressure retaining bolting installation.
The procedure actually required QC inspection of this attribute.
The deviation from procedure IX-48 was documented in Deviation Report (DR)
PP-17 587.
Engineering dispositioned the DR
" Hardware Not Affected" with no further action required for resol ution.
This disposition was based on the fact that the bolting installation was verified to be acceptable by the Equipment Field Engineer and an equipment supplier representative who was present.
A broadness review of documentation for equipment assembly and installation was performed by PPP to determine if additional instances 3
had occurred whereby field engineers performed verification / documentation of attributes requiring QC inspection.
The review covered process sheets completed on or after April 2,
1987, the effective date of the revision to PPP procedure IX-48.
No additional cases were found.
Therefore, the violation is attributed to an isolated case of personnel error.

To prevent further violations, the Equipment Field Engineer was reinstructed in the requirements of procedure IX-48.
In adaition, c
the following procedural revisions and program enhancements have been accomplished to address other USNRC Jncerns related to the violation.
PPP Procedure IX-48 and the process sheet form have been revised to distinguish between QC and field engineering hold points.
The hold point block is now labeled " Hold for PPP QC/FE."
A diagonal line has been drawn across each block.
Hold points for QC inspectors I
will be designated in the upper left portion of the block and hold points for field engineers will be designated in the lower right portion.
l l
PPP procedures IX-48 and IX-5 have been revised to clearly delineate l
the functions of QC and field engineering to inspect / verify torquing
{-
of ASME pressure boundary pipe.
QC inspects torquing of ASME pipe-to-equipment bolted connections.
Field engineers verify acceptable torquing for ASME pipe-to-pipe bolted connections.
QC inspectors are not required to inspect torquing of ASME pipe-to-pipe l
bolted connections since the mechanical joints are subsequently l
pressure tested to assure integrity and the testing is inspected l
by QC.
Procedure IX-48 and the inspection / verification checklist have been revised to change the column heading from "PPP Inspection and Date" to " Verified By, Date."
This change, in combination with the new method for designating hold points provides a clear indication of whether the line item was inspected by QC or verified by field engineering.
All corrective actions to resolve the violation, as well as the additional program enhancements, have been completed.
Appropriate construction personnel have received instruction in the program changes.
This response contains no proprietary information and may be placed in the USNRC Public Document Room.
