APPENDIX A NOTICE OF VIOLATION Tennessee Valley Authority License No. CPPR-162 Phipps Bend Nuclear Plant Based on the NRC inspection December 11-14, 1979, certain of your activities were apparently not conducted in full compliance with NRC requirements as indicated below. These items hav-been categorized as described in correspon-dence to you dated December 31, 1974.
A.
As required by Criterion V of Appendix B to 10 CFR 50 and as implemented by paragraph 17.1A.5 of the PSAR, "\\ctivities affecting quality shall be prescribed by documented instructions, procedures and drawings... and shall be accomplished in accordance with the:e instructions, procedures and drawings." Paragraph 14.9 of process specificar. ion 1.M.I.2(b) of General Construction Specification G29M, applicable to containment shell welding, limits the bead width resulting from weaving to 5/8-inch maximum for the gas metal arc (including flux cored) process.
Contrary to the above, on December 12, 1979, bead widths of 3/4-inch to 7/8-inch on containment shell welds IT 2301629 and IT2301631, welded with the flux cored process, were observed. Discussions with inspection personnel revealed that weaving the full width of the joint until the joint is full has been the practice in the past. This results in a bend width of one-inch or greater at the top of the joint.
This is an Infraction.
B.
As required by Criterion V of Appendix B to 10 CFR 50 and as implemented by paragraph 17.1A.5 of the PSAR, " Activities affecting quality shall be prescribed by documented instructions, procedures and drawings... and shall be accomplished in accordance with these instructions, procedures and drawings." Paragraph A.0 of QCI N-501, the applicable proce6/re for fitup inspection of welds, requires in part, "All welds requiring fitup examina-tion shall be examined for compliance with the applicable welding procedure, drawings..." Paragraph 7.0 requires in part, "As a minimum the following information shall be recorded for each examination for which documentation is required by the Quality Assurance Procedures.... i. Results of Inspections" Contrary to the above, on December 11, 1979 results of fitup inspection were not accurately recorded for containment base liner plate weld IT00029 in that the fitup was signed off as being acceptable when in fact the root gap did not meet drawing requirements.
This is an Infraction.
