Nuclear Regulatory Ccmmission-Finding 10CFR 50,' Appendix B, Criterion IX states in part: " Measures shall be established to assure that special processes, including welding, . . .

are controlled and accomplished . . . using qualified procedures in accor-dance with applicable codes, standards, specifications, criteria, and other special requirements."

Paragraph 17.4.9 of the Quality Assurance Program documented in the PSAR states in part: "

. . . Special procedures prepared by site contractors will be qualified when required in accordance with applicable codes and standards . . ."

The electrical installation contract specification (No. 3240-225/253) spe-cifies that electrical cable tray support welding shall be accomplished in accordance with the AWS Structural Welding Code DI.I. The Structural Weld-ing Code states that procedures must be qualified unless certain requirements are met. Among these requirements is that fillet welds must meet minimum size requirements for various base metal thicknesses. For example, for base metals thicker than 3/4 inch the minimum fillet weld size is 5/16 inch. The electrical cable tray support drawings (e.g., Dwg. No. SS-27 for supports E-162 through E-165) ' designate 3/16 inch fillet welds for base material thicknesses of 1.26 inches. In additian, approved Field Change Request No. FCR-F-1017 of January 14, 1981, for Contract No. 3240-225/253 specifies that the con-tractor's fillet weld procedure must be qualified.

Contrary to the above, as of March 26, 1981, the contractor had not qualified his fillet welding procedure, yet had used this procedure for the welding of all safety-related cable tray supports.

This is a Severity Level V Violation (Supplement II), applicable to Unit 3 only.

• Nuclear Regulatory Comission-Finding Corrective Steps Which Have Been Taken:

1. When notified of the item of noncompliance, Fischbach & Moore (F&M)

Inc., 3240-225/253 contractor, had previously stopped welding Class I seismic supports as a result of F&M Stop Work Order (SWO) 002.

F&MSWO002wasissuddMarch 13, 1981, for reasons other than weld-ing. Subsequently, the Stop Work corrective action allowed for re-lease of material for fabrication and installation. All welding on supports released for fabrication was performed to qualified welding procedures.

2. To preclude use of unqualified multiple pass fillet welds during in-stallation, F&M IOM, A. N. McLeod to J. A. Wiley, dated April 22, 1981, prohibited the use of all multiple pa:: welds until a procedure was qualified.

3. F&M 104, A. N. McLeod to J. A. Wiley, dated April 27, 1981, rescinded the 10ft in Item 2 and clarified use of multiple pass welds to those covered by Table 2.7 of AWSDl.l.

4. Upon completion of F&M's investigation of multiple pass welds performed prior to notification of the noncompliance, F&M issued NCR 225-3036 on April 28, 1981. This NCR is presently being evaluated by Ebasco.

Corrective Steos Which Have Been Taken To Avoid Further Violation:

1. On fisrch 31, 1981, F&M initiated qualification of welding procedure AWS-1A. The welding process and record was incorporated into CP-403S3, j l

Revision 4, " Welding of Steel Structures," on April 1,1981. I i l l-

2. On April 21, 1981, F&M roted that AW'i-1A was not qualified in accor-i dance with code requirements and necessitated requalification of the l procedure. Between April 1 - April 21, no unqualified welds were per-formed.

.. , :D e; , , . - * '

t

3. On April 28,1981, F8M requalified welding procedure AWS-1A and incor-Jporated this record in Revision 5 of CP-403S3, on May 1,1981.

Date-When Full ~ Compliance Will Be Achieved:

CP-40353, Revision 5, was approved on May 8,1981. . Training of F&M per-sonnel and craft will be accomplished by June 1,.1981.
