ggg-APPENDIX A NOTICE ~0F~ VIOLATION Washington Public Power Supply System P.O. Box 1223 Elma, Washington 98541 Docket Nos. 50-508, 50-509-Construction Permit Nos. CPPR-154, CPPR-155 As a result of the inspection conducted on March 2 to 27, 1981, and in
'accordance with the Interim Enforcement Policy, 45 FR 66754 (October 7, 1980), the following violation was identified:
10 CFR $0, Appendix B, Criterior. IX states in part:
" Measures shall be established to assure that special processes, including welding,... are controlled and accomplished... using qualified procedures in accordance with applicable codes, standards, speci-fications, 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) specifies that electrical cable tray support welding shall be accomplished in accordance with the AWS Structural Welding Code DI.I.
The Structural Welding 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 addition, approved F' eld Charge Request No. FCR-F-1017 of January 14, 1981, for Contract No. 3240-225/253 specifies that the contractor'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 proce-dure for the welding of all safety-related cable tray supports.
This is a Severity Level V Violation (Supplement II), applicable to Unit 3 only.
