06/25/84 SSER Task: Allegation A-226, A-306b, A-306f, A-306o, A-306p 4-84-A-0gjl14),f84 2,IBy[j t89o, /8 Yy Ref. No.:
Characterization: It is alleged that the traceability requirements of permanent attachment material welded to Class 1 and 2 piping pressure boundaries by Tompkins-Beckwith (T-B) were not satisfactorily resolved by EBASCO Engineering.
Assessment of Allegation:
In assessing this allegation, the NP,C staff reviewed LP&L's Preliminary Safety Analysis Report (PSAR) and the Final Safety Analysis Report (FSAR), as well as the appropriate sections of the EBASCO contract documents. The staff found that design of piping systems is based on LP&L's comitment to the Winter 1972 Addenda in Section III of the ASME Code. Since welded attachments are not pressure-retaining components, the only Code requirement is that the attachments must be made of materials pennitted by the applicable ASME Code section.
Code Class 1 welded attachments need be in conformance with material specifications in subsections NB-2121 and NB-4435 of the Code. Certified Material Test Reports (CMTRs) are required and are included in the piping documentation package.
Code Class 2 welded attachments need be in conformance with material specifications in Appendix I, Table I-7.0, of subsections NC-2190 and ND-2190 of the Code. CMTRs or Certificates of Compliance (C of C's) are required and are included in the piping documentation package.
The NRC staff determined that either CMTRs or C of C's for permanent attachment material are included in piping documentation packages. Accordingly, the NRC staff concludes that the material traceability requirements of welded attachments to Class 1 and 2 pressure boundaries have been properly resolved.
In addition, these weld attachments were inspected by an authorized nuclear inspector.

Characterization: It is alleged that the traceability requirements of j
permanent attachment material welded to Class 1 and 2 piping pressure boundaries by Tompkins-Beckwith (T-8) were not satisfactorily resolved by EBASCO Engineering.
Assessment of Allegation:
In assessing this allegation, the NRC staff reviewed LP&L's Preliminary Safety Analysis Report (PSAR) and the Final Safety Analysis Report (FSAR), as well as the appropriate sections of the EBASCO contract documents.

welded attachments are not pressure-retaining components, the only Code requirement is that the attachments must be made of materials permitted by the applicable ASME Code section.
Code Class I welded attachments need be in conformance with material specifications in subsections NB-2121 ard PS 4435 of the Code. Certified l
Material Test Reports (CMTRs) are required and are included in the piping documentation package.
Code Class 2 welded attachments need be in conformance with material specifications in Appendix I, Table I-7.0, of subsections NC-2190 and ND-2190 l
of the Code. CMTRs or Certificates of Compliance (C of C's) are required and are included in the piping documentation package.
