g APPENDIX A Washington Public Power Supply System P.O. Box 968 Richland, Washington 99352 t
Docket flos. 50-460 Construction Permit No. CPPR-134 NOTICE OF VIOLATION Based upon the results of NRC inspection activities conducted by the resident inspector during the period of December 1-31, 1979, 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.
Criterion 9 of Appendix B of 10CFR50 requires that measures shall be established to assure that special processes, including welding...,
are controlled and accomplished by procedures, in accordance with appli-cable codes, standards, specifications, criteria, and other special requirements. Section 17 of the PSAR describes implementation of Appendix B, and Section 3.12 describes Regulatory Guides 1.31 and 1.44.
The WPPSS contract specification #257 Section 17A-3 item 3.1. 2.1 requires that " Weld procedures shall include instructions governing heat input---bead width shall be maximum of 3 times the core diameter for the manual SMAW." The contractor procedure JAJ-WP-P8-1 includes instructions on weld technique, regarding oscillation, -- 3 times electrode core diameter.
(i.e.,3/8-inchmaximumweave.)
Contrary to the above, on December 17, 1979, examples where the maximum width of 3/8-inch weld weave was exceeded were identified in auxiliary feedwater and purification system piping in completed and inspected welds numbered F411499-021 and F411975-006. These welds contained excessive weaves of 3/4-inch and 5/8-inch respectively.
This is an infraction.
