WPPSS NUCLEAR PROJECTS NOS. 1/4

DATES OF INSPECTION - JUNE 2-9, 1980
DOCKET NOS. 50-460 AND 50-513

Reference:
Letter from G. S. Spencer to N. 0. Strand, NRC Inspection
at WNP-1/4 Site, dated July 17, 1980.
The referenced correspondence delineated the results of the June 2-9,
1980 inspection of activities authorized by NRC Construction Permits
Nos. CPPR-134 and -174.
Further, the referenced correspondence identified
a certain activity which was not conducted in full compliance with PSAR
requirements set forth in the Notice of Violation enclosed as Appendix A.
This item of noncompliance has 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 finding, as identified, and the Supply System response is
provided herewith as Appendix A.
Very truly yours,

APPENDIX A
Nuclear Regulatory Comission
Region V
Suite 202, Walnut Creek Plaza
1990 fl. California Boulevard
Walnut Creek, California 94596
Docket flo. 50-460
Construction Permit No. CPPR-134
.
Based on the results of NRC inspections conducted during the period of June 2-9,
1980, it appears that one of your activities was not conducted in full compliance
with conditions of your NRC Construction Permit No. CPPR-134 as indicated below:
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 instruc-
tions, procedures or drawings, of a type appropriate to the circumstances
and shall be accomplished in accordance with these instructions, pro-
cedures or drawings . . .."
Allied-Capitol Jaint Venture Drawing No. FCN-495, Revision 1, specifies
5/16-inch fillet welds for structural steel column No. 2270A and a 1/2-inch
fillet weld for the attachment clip on column No. 2283. Contract specifica-
tion No. 207 requires these columns to be fabricated in accordance with
requirements of the AWS D1.1 structural welding code. This code permits
fillet weld size to underrun the specified nominal fillet weld size by
1/16-inch without correction provided that the underrun does not exceed
ten percent of the length of the weld.
Contrary to the above, on June 2,1980, the sizes of fillet welds on column
,
No. 2270A were less than 1/4-inch over the full length of the welds and the
!
attachment clip fillet weld on column No. 2283 was 3/8-inch or less over
the full length of the weld.
This is an infraction.

SUPPLY SYSTEM RESPONSE
Corrective Action Taken and Results Achieved
An indepth review of. the Contract 207 drawing indicates that structural member
2283, as referenced in this report, is actually 2283A.
-The undersized welds on structural members 2270A and 2283A are documented on
Nonconformance Report No. 4-NCR-207-056 dated June 4, 1980. The aforementioned
Nonconforcunce Report also includes four (4) additional structural members that
contained undersized welds (piece marks 22, 67A, 2271A, 2348A and 3259A). All
of the affected structural members have been appropriately hold tagged.

Corrective Action Taken and Results Achieved (Cont'd)
flonconformance Report flo. 4-flCR-207-056 is pending Engineering evaluation. Dispo-
-
sition action as required will be accomplished a'ter our current labor situation
is resolved.
As a result of.this flotice of Violation, the Supply System initiated a re-inspec-
tion of all structural steel members in the WflP-1 and WilP-4 storage areas.
In
addition, similarLinspections of accessible erected steel in the general services
buildings and containment buildings are in progress. All defective welds will be
identified, and appropriately tagged. flonconformance reports will be initiated,
as required.
Action Taken to Preclude Recurrence
Project Quality Assurance and UE&C Vendor Surveillance met with Capital Steel
Corporation personnel on August 5-8, 1980 to review acceptance criteria practices
in the shop and to inspect the-balance of structural steel for shipment.
All future shipments will receive a 100% inspection instead of the random sampling
by the UE&C Vendor Surveillance Representative.
All structural members in the storage areas that require rework will be reinspected
by Project Quality Assurance personnel prior to release for installation.
Date of Full Compliance
Full compliance will be achieved when the current labor situation is resolved.
We will advise you of the date of full compliance by written communication.
