Reference:
Letter from G. S. Spencer to R. L. Ferguson, NRC Inspection at WNP-1/4 Site, dated October 7,1980.
The referenced correspondence delineated the results of the August 26-29 and September 9-12 1980 inspections of activities authorized by NRC Construction Permits Nos. CPPR-134 and -174.
Further, the referenced correspondence identified certain activities which were not conducted in full compliance with PSAR requirements set forth in the Notice of Violation enclosed as Appendix A.
These items of non-compliance have been categorized into a level as described in your correspondence.to all NRC licensees dated December 31, 1974.
This letter is submitted in response to the referenced correspondence. The specific NRC findings, as identified, and the Supply System response is provided herewith as Appendix A.
Very truly yours,

fl0TICE OF VIOLATION l
Based on the results of NRC inspections conducted during the period of August 26-29 and September 9-12, 1980, it appears 'that certain of your activities were not conducted in full compliance with conditions of your NRC Construction Permit No. CPPR-134 as indicated below:
A.
10 CFR 50, Appendix B, Criterion V, as implemented by Section 17.1.5 of j
the quality assurance program documented in the PSAR and the WPPSS QA Program Manual Procedure QAP-2, Paragraph 3.1, states, in part, that
" Activities affecting quality shall be prescribed by documented in-I structions, procedures or drawings, of a type appropriate to the circum-stances and shall be accomplished in accordance with these instructions, procedures or drawings...."
Detail drawing no. DHRX-35 (WPPSS drawing no. 9779-F-412030, Revision 3) for pipe spool DHR 412030-2 of the decay heat removal system specified 5/16" fillet welds for the attachaent of eight pipe stop blocks to the spool piping.
I Contrary to the above, on August 27, 1980, two welas attaching two pipe j
stop blocks to the pipe were 1/4" fillet welds. These welds had been inspected and accepted by the vendor ( B. F. Shaw) on April 24, 1980.
This is an infraction.
SUPPLY SYSTEM RESPONSE a
Corrective Action Taken and Results Achieved On August 28, 1980, Project Quality Assurance performed an inspection of the pipe spool in question.
Six of eight lugs were found to be l
undersized. This condition was documented on 1-NCR-137-190.
l On September 2,1980 additional surveillance was performed on a random sample of fifty-four (54) pipe spools for identification of similar conditions. Of this sample, no spools with lugs were found in the lay-i down area.
Additionally, thirty drawings were checked on site to identify other pipe spools which have shop-welded lugs. Five such drawings were found, having a total of fifteen pipe spools identified as having shop welded lugs. A search of CMCP (Coordinated Material Control Program) revealed that none of the fifteen spools has been received on site.

Action Taken to Preclude Recurrence This condition is extremely isolated and will be corrected in accordance with the disposition of 1-NCR-137-190. UE&C Engineering is currently evaluating this condition.
10 CFR 50, Appendix B, Criterion V, as implemented by Section 17.1.5 of the quality assurance program documented in the PSAR and the WPPSS QA Program Manual Procedure QAP-2, Paragraph 3.1, states, in part, that
" Activities affecting quality shall be prescribed by documented instruct-ions, procedures or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, pro-cedures or drawings...."
Procedure No. FGCP-48, Revision 0 (Corrective Maintenance Management),
specifies in paragraph 5.0 that "All maintenance performed under the Maintenance Management Program will be accomplished by Maintenance Work Request." This procedure is applicable to repair or modification work required on prepurchased material.
Contrary to the above, during the period August 26-27, 1980, five arc strikes were removed from pipe spool no. DHR-412030-2 without using a Maintenance Work Request to authorize the work. Additionally, no records were provided to document the methods used to remove the arc strikes nor examine the repaired areas. This pipe spool is prepurchased material for the decay heat removal system, 1
This is an infraction.
SUPPLY SYSTEM RESPONSE Action Taken and Results Achieved This condition was documented on a Corrective Action Request (1-CAR-257-12).
A nonconformance report (1-NCR-CM-382) has been written documenting the fact that the arc strikes were removed without authorization and sub-i sequent NDE exam by liquid penetrant. An FCN will be generated to JA Jones to perform and document required NDE on the affected areas.
Action Taken to Preclude Recurrence JA Jones has an approved procedure (JAJ-WI-030) for Weld and Base Metal Repair.
Although JA Jones does not admit fault in this incident and it cannot be determined how the arc strikes were removed due to the labor dispute in force at the time, JA Jones has committed to provide indoctrination of affected personnel upon return of the craf ts to emphasize the necessity of proper authorization of work anu subsequent documentation.
