l Appendix A NOTICE OF VIOLATION Union Electric Company Docket No. 50-483 Based on the results of an NRC inspection on July 15 - 18, 1980, it appears that some of your activities are in noncompliance with NRC requirements as noted below. All the items are infractions.
1.
10 CFR 50, Appendix B, Criterion III states, in part that, " Measures shall be established to assure that applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures, and instructions".
The SNUPPS Project Quality Assurance Manual in Section 17.1.3 states in part, that, "the SNUPPS utility quality assurance program requires that the design of safety-related structures, be controlled so that applicable regulatory requirements and design bases are properly translated into specifications and drawing."
The following examples were contrary to the above:
a.
Specification E-050 (Q) for batteries and battery racks did not establish requirements for protecting the integrity of installed battery racks by specifying the use of acid resistant paint after field installation; as a result, carbon steel angle iron battery rack supports welded to the embeds exhibit rust where paint was damaged during installation. Furthermore, the field welds were not required to be painted with acid resistant paint to prevent deterioration.
b.
No special requirements, such as acid corrossion resistance, which would withstand the atmosphere surrounding it's installation were specified for the hardware used to assemble the seismic Category I battery racks.
2.
10 CFR 50 Appendix B, Criterion VII states in part that, " Measures shall be established to assure that purchased material, equipment, and services whether purchased directly or through contractors and subcontractors, conform to procurement documents.
The SNUPPS Project Quality Assurance Manual is section 17.1.7 states in part, that, "The SNUPPS utilities quality assurance program established controls to assure that purchased material...
conform to the pro-curement document or these measures shall include provisions...and examination of products upon delivery."

Appendix A Contrary to the above, it was determined that some of the welds on the Main Control Panel did not conform to the purchase specifications.
3.
10 CFR 50 Appendix B, Criterion IX states in part that, " Measures shall be established to assure that special processes, including welding.
. are controlled and accomplished by qualified personnel using qualified procedures in accordance with applicable codes,.
and other requirements."
The SNUPPS Project Quality Assurance Manual in Section 17.1.9 states in part, that, "The SNUPPS utilities require that special processes be controlled. Special processes will be accomplished.
. with applicable codes... or other special requirements."
American Welding Society D1.1-76 code paragraph 2.8.2 states, "The maximum diameter of the hole for a plug weld shall not be greater than 2 1/4 times the thickness of the weld."
Contrary to the above, 9/16" diameter holes on 1/8" thick angle iron battery rack supports were plug welded. The Welding Quality Control Surveillance Reports (WQCSR) documenting weld inspections on one of the battery rack supports indicates that plug welds were inspected and determined acceptable.
WQCSRs for battery racks NK12 and 13 contain inadequate information as to the number and type of welds inspected.
