Report Number: WP-09-SON. R1 Report
Title:
WELD INSPECTION CRITERIA USED FOR SON CONSTRUCTION I. SCOPE OF EVALUATION This engineering analysis covers WBN Employee Concern Number IN-85-406-002 which was deemed to have possible generic implications at SQN.
i' II. ISSUES ADDRESSED BY CONCERN (S)
.The subject concern was analyzed to determine the issue voiced by the concerned individual (s). This issue is as follows:
Prior to 1979, there was no specific weld inspection criteria for use by inspection personnel.
.III. CONCERN VALIDITY OR SUBSTANTIATION
, The base requirement for inspection procedures comes from Criteria V snd X of 10 CFR 50, Appendix B, and ANSI N45.2. The principle of inspection procedures is a basic and integral part of the TVA Quality Assurance Program. The SQN Division of Construction Quality Assurance Program included the requirement for procedural control of quality
, affecting/ quality assuring activities in SNP Construction Procedure No. P-1, " Preparation of Construction Procedures and Inspection Instructions," which was originally issued on December 16, 1971.
Inspection procedures were generated in accordance with the provisions of this document and were issued for use at SQN.
1 General Construction Specification G-29 was first formally transmitted l to~the implementing organizations on July 22, 1971. This specification l contained the weld inspection acceptance criteria and technical lR1 documentation requirements. l The Division of Construction (now OC) at SQN originally conveyed the l requirements in site implementing procedures. These procedures were l oriented by engineering discipline responsible for the feature. The l ,
- documentation requirements were specified in checklist format and the l appropriate G-29 process specification was referenced for the acceptance l criteria. l l

- 8. SNP-M-27 issued 5/28/76 " Fabrication, Installation, and ]
Cleanliness Requirements for Heating Ventilating, and l Air-Conditioning Duct Systems" l 1
Restructure of the Site Quality Assurance Procedures in 1977 resulted in the l following specific Inspection Instructions conveying the welding inspection lR1 criteria by the type of inspection being performed: l l
- 1. SNP-II-74 issued 2/14/77 " Fit-Up and Cleanliness Inspection" l 1
- 2. SNP-II-75 issued 1/31/77 " Visual Examination of Welded Joints" l l
i
- 3. SNP-II-76 issued 3/16/77 " Liquid Penetrant Inspection" l I
- 4. SNP-II-77 issued 3/16/77 " Magnetic Particle Inspection" l
' l SNP-II-78 issued 2/22/77 " Ultrasonic Examination" l 5.
l
- 6. SNP-II-79 issued 4/22/77 " Radiographic Examination" l This network of procedures provided the basis for welding inspection activities at SQN during construction. The Welding Project has reviewed these procedures and determined that the necessary detail was present and that the l requirements were accurately presented.
Overviews by the TVA QA organization and by NRC inspectors were routinely performed during the construction of Sequoyah Nuclear Plant. (These overviews have continued during the operational phase.)-
Procedural deficiencies noted by overviews were tracked, corrected, and closed during the appropriate timeframe.
I In addition, the Bechtel SQN Implementation Audit performed in January 1986 directly examined the adequacy of inspection procedures and their l
' implementation in Key Element 10.0, "Use of Approprince Inspection Procedures" (attached). The audit indicated that the review of the inspection procedures showed compliance with TVA program requirements and referenced codes and standards.
l In summary, the issue considered in the concern is not substantiated due to the l following factors:
l l
Page 2 of 3 00280
~
WP-09-SQN, R1
- 1. Inspection procedures which delineated cede and standard requirements were in effect at SQN for OC.
- 2. The Bechtel SQN Implementation Audit provides an independent verification of the adequacy of these procedures.
Based upon the foregoing analysis, the issue addressed in this Employee Concern is closed.
