Report

Title:

WELDER TRAINING PROGRAM FOR CONSTRUCTION AND OPERATION I. SCOPE OF EVALUATION This engineering analysis covers the following WBN and BLN concerns deemed to have possible generic implications to SQN: IN-85-706-001 XX-85-045-001 EX-85-008-001 lR1 II. ISSUES ADDRESSED BY CONCERNS Each concern was analyzed to determine the issues voiced by the concerned individuals. These issues are as follows:

1. The TVA Welder Training Program is inadequate for nuclear construction.
2. Welder performance qualification tests do not test a welder's overall ability.

() III. CONCERN VALIDITY OR SUBSTANTIATION SQN and other TVA construction sites have historically had extensive welder training programs. SQN had a welder training facility in

                             . operation frc:a the beginning of construction at SQN until approximately
                             ~1981. This training program put heavy emphasis on individual Instruction end training to perform specific tasks such as open butt GIAW pipe welding. Instructors were craftsmen with considerable skill and experience in all aspects of welding.-

There is no regulatory requirement which mandates a welder training program. These programs were developed for the purpose of development of a qualified labor pool of welders from which expert craftsmen could be drawn who would be capable of performing quality work in an efficient manner. This is a prudent business practice. These programs also increased the probability that welders would pass the welder performance qualification test prior to making production welds. The requirements for wolder performance qualification testing outlined in AWS, ANSI, and ASME B&PV Codes address the issue of skill level. These codes state that the purpose and intent of individual welder performance qualification tests are to determine the welder's ability to produce sound welds. This qualification test is the requirement mandated by codes and standards to determine the minimum skill level of welders, not the content or existence of a welder training program. 3-e Page 1 of 2 00410 ,

                 -                            The requirements for welder performance qualification tests are                                                                     1
         --                                   incorporated into both the OC and NO Quality Assurance Programs, and                                                               j their details are well documented. They have been audited through the ASME Implementation Survey for Certificates of Authorization and by                                                                 ;

1 organizations such as INPO and NRC. The Bechtel SQN Implementation Audit performed in January 1986, .. directly addressed this issue in Key Element 3.0, " Initial Welder or Welding Operator Qualifications," Key Element 4.0, " Maintenance of Welder or Welding Operator Qualifications," and Key Element 5.0, > " Renewal of Welder and Welding Operator Qualifications." For both OC and NO, the audit indicates that the programs met upper-tier - commitments and were effectively implemented. The SQN Reinspection Program also provides objective evidence of welder skill. No substantial welding problems were discovered which were attributable to welder skill. . In summary, the issues considered in these concerns are not substantiated due to the following factors:

1. There is no requirement relative to welder training prograss.
2. The base requirement for welder skill is the Welder Performance
Qualification Test Program.
1) 3. The Welder Performance Qualification Test Program is outlined in both the OC and NO QA programs.
4. The Bechtel SQN Implementation Audit has established that these programs have been and are being effectively implemented by OC and

! NO. f 5. No indications of a generic welder skill problem was discovered by the SQN Reinspection Program. l Based on the forescing analysis, the issues considered in these concerns are closed. Na' Page 2 of 2 L 00410
