Appendix B of 10CFR50, Criterion V, as addressed in Paragraph 5.1 of the Quality Assurance Program in Appendix A to the PSAR, states,.in part: " Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings..."
Bechtel Drawing No. 13-C-ZCS-655, Revision 2, which governs structural steel column' fabrication, in Section G, " Weld Detail",~ depicts h" fillet welds on the outside of the column.
flange to base plate intersection.
Contrary to the above, on January 28, 1982, three columns at the 149' Elevation'of the Unit ~1 Containment Building were 4

Corrective Steps That Have Been Taken To Avoid Further Noncompliance a.
Corrective Action Request S-82-13 was issued to supplier, Marathon Steel Company-on February 4,1982, requesting investigation to determine cause and corrective' action to l
prevent recurrence.

Subsequent inspection by Marathon found three additional columns with missing welds, two on Unit 1, one on Unit 3.
Nonconformance Report NCR-CC-3253, dated February 23, 1982, was issued for the Unit 3 column and NCR-CC-3279, dated March 4, 1982,-was' issued for the Unit 1 columns.
e NCR CC-3279 was dispositioned Rework on March 11, 1982 and the Rework was accepted by QC Engineer on March 25, 1982, e NCR CC-3253 was dispositioned Rework on February 26, 1982 and the Rework was completed on April 13, 1982.
3.
Date When Full Compliance Will Be ' Achieved The reinspection effort by Marathon Steel was initially started e
on February 10, 1982 and was completed on March 10, 1982.
Marathon's answer to the CAR S-82-13 and Letter B/MSC-K-10037 e
states that the deficiency is the result of an unclear method of weld detail.
All column drawings containing this type of detail were noted and tabulated for the field reinspection effort that was completed on March 10, 1982. This condition will also be highlighted or changed on all future detail drawings as they are reviewed by Marathon's Project Engineer.
e As of April 13, 1982, full compliance has been achieved.
NOTE:
All supporting documentation for the above is on file in the Bechtel PVNGS Site QA office.
