7 APPENDIX A NOTICE OF VIOLATION Baltimore Gas and Electric Company Docket / License Nos.:
50-317; DPR-53 Calvert Cliffs Nuclear Power Plant 50-318; DPR-69 During an NRC inspection conducted from November 15, 1989 through December 31, 1989, and in accordance with the NRC Enforcement Policy (10 CFR Part 2, Appendix C), the following violations were identified.
i 10 CFR 50, Appendix B, Criterion XIII, " Handling, Storage and Shipping," and the Calvert Cliffs Quality Assurance Plan state that measures shall be estab-lished to control the storage and preservation of equipment in accordance with work and inspection instructions to prevent damage or deterioration.
1.
Chemistry Procedure (CP) 217, " Specifications and Surveillance - Steam Generators," implements the above requirements and specifies that, during cold shutdown and refueling modes, steam generator secondary side water pH should be maintained between 9.8 and 10.5 and hydrazine concentration should be maintained between 70 and 200 ppm. CP-217 also states that if a parameter degrades beyond its specifications, it should be returned to within specification to prevent corrosion to the steam generators.
Contrary to the above, between May 1,1989 and December 15,1989, the pH levels and hydrazine concentrations for steam generator Nos.11,12, and 22 were not maintained within the required specifications.
This is a Severity Level IV Violation (Supplement I).
2.
Title 10 CFR 50, Appendix B, Criterion V requires that activities affec-ting quality shall be prescribed by documented instructions, procedures or drawings, of a type appropriate to the circumstances and shall be accom-plished in accordance with these instructions, procedures or drawings.
l The applicable electrical cable installation and separation requirements are implemented in " Design and Construction Standards for Cable and Race-way" (E 406).
E 406 requires that each of six cable separation groups be i
physically separated from one another horizontally (three feet minimum) l and vertically (five feet minimum) or by an intervening barrier.
1 Contrary to the above, the following examples of inadequate cable separation were identified:
