Vogtle Electric Generating Plant - Unit 2 USNRC Inspection Report 50-425/87-10 The Georgia Power Company wishes to submit the following information concerning the violations identified in the referenced inspection report.
Violation 50-425/87-10-02, " Failure to Follow Procedures for Control of Welding Activities" - Severity Level V Georgia Power Company (GPC) acknowledges the violation as identified in the USNRC inspection report.
The violation is attributed to inadequate training of electrical contractor (Cleveland Electric) welders relative to color-coding of grinding wheels.
When the discrepancy was identified by the USNRC inspector, GPC promptly issued a procedure awareness flyer (PAC 2-87-14) to inform Cleveland welders of the potential problem associated with color-coded grinding wheels and other tools.
A special surveillance was performed by GPC welding section personnel which concentrated on the use of color-coded tools for grinding, brushing, and filing welds.
The surveillance determined that the problem of using red-coded tools on carbon steel was limited to isolated occurrences involving Cleveland welders.
Welders working for other contractors were observed to be implementing (PAC 3-87-3) was issued to Cleveland welders to provide proper tool controls.
Therefore, another procedure awareness flyer additional training on proper tool control and to instruct them to paint blue any red-marked tools currently in their possession.
The tool marking has been completed, thus preventing their usage on any material other than carbon steel.

GN-1366 Page two To prevSnt further violations, the general welding control procedure (GD-T-13) was revised on February 26,
- 1987, to include tool color-coding requirements. Appropriate toolroom personnel were trained in implementing the revised procedure.
To prevent possible cross-contamination of tools in the toolroom storage bins, grinding wheels are now removed prior to placing tools in the bins and the wheels are stored separately.
Also, Cleveland welders requesting red-coded tools must have supervisory approval before the toolroom attendants can issue the tools.
As a precautionary measure, additional training in proper tool controls was provided to other site contractor personnel involved in welding activities.
This training was accomplished primarily through " gang box" training sessions.
Another special surveillance was conducted by GPC welding section personnel on April 1, 1987, to determine the effectiveness of the corrective actions described above.
The surveillance yielded satisfactory results.
Full compliance with applicable requirements has therefore been achieved.
Violation 50-425/87-10-03. " Failure to Accomplish Adequate Corrective Action" - Severity Level IV Georgia Power Company (GPC) acknowledges the violation as identified in the USNRC inspection report.
The violation is attributed to personnel error in that the engineer's reference copy of a work package was issued to a craftsman without first being checked for uncontrolled copies of design documents.
The installation work package which ordinarily would have been used, and which contained the controlled copy of Field Change Request V-FCRB-103, was temporarily mislocated.
To avoid delays, the engineer's work package was issued to the craftsman.
The engineer's work package contained a reference (pink) copy of the field change request that was not intended for craft use.
When the discrepancy was identified by the USNRC inspector, the pink copy of the field change request was promptly replaced with a controlled copy.
It should be noted that the pink copy was the latest design and installation work was not impacted by the discrepancy.
The individuals involved in the error were identified and appropriate disciplinary action was taken.
In addition, a thorough search was conducted of Unit 2 work stations (including gang boxes, desks, etc.)
and all pink drawings found in the field were confiscated.
No instances were found where work was being performed to out-of-date drawings.
To prevent further violations, a procedure awareness flyer (PAC 2-87-12) was issued to appropriate engineers and craftsmen to re-emphasize the project policy relative to the use of uncontrolled

GN-1366 Page three copies of design documents and to remind personnel of the proper procedures for the maintenance and control of design documents.
Work packages are now required to be reviewed by field engineers prior to issuance to craftsmen to ensure no uncontrolled design documents are included.
In addition, surveillance of craft work packages while installation work is being performed has been added to the scope of routine Electrical Field Operations drawing control compliance monitoring activities.
All corrective actions have been completed and compliance with applicable reqJirements has been achieved.
These responses contain no proprietary information and may be placed in the USNRC Public Document Room.
