ENCLOSURE 1 NOTICE OF VIOLATION Duke Power Company Docket Nos. 50-369, 370 McGuire Units 1 and 2 License Nos.NPF-9, NPF-17 During the Nuclear Regulatory Commission (NRC) inspection conducted on i

l January 21, 1988 through February 26, 1988, a violation of NRC requirements was i

identified. In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1987), the violation is identified below:

Technical Specification (TS) 6.8.1.a. requires that written procedures be established, implemented, and maintained covering the activities delineated in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.

Regulatory Guide 1.33, Revision 2, February 1978, Appendix A, requi res,

in part, that instructions be prepared for energizing, filling, venting, draining, startup, shutdown and changing modes of operation of safety related systems including emergency power sources (e.g. diesel generator, batteries) and the chemical and volume control system (including letdown / purification system).

McGuire Nuclear Station Procedure IP/0/A/3061/08, Water Addition and Equalizing Charge for Vital Batteries, step 10.4.3. requires an output voltage of 141.0 VDC to be established to conduct an equalizing charge on the vital batteries.

McGuire Nuclear Station Procedure OP/1/A/6200/01 Enclosure 4.7 provides instructions for removing the chemical and volume control (NV) system cation bed demineralizer from service.

1.

Contrary to the above, procedure IP/0/A/3061/08 was not properly implemented in that an output voltage of approximately 148 VDC rather l

than the required 141.0 VDC was being used on February 10, 1988, when conducting an equalizing charge on vital battery EVCB.

Instrument and Electrical (IAE) technicians and engineers were aware of the procedural requirement to establish 141.0 VOC but chose to establish a higher voltage without making the required change to the procedure.

l 2.

Contrary to the above, the procedure for removing the cation bed l

demineralizer from service, OP/1/A/6200/01 Chemical and Volume Control System, was not properly maintained in that steps were changed during a revision leading to overpressurization of the system.

This overpressurization on February 3, 1988, led to the rupture of the diaphram on valve INV-474 and a contaminated spill.

i I

This is a Severity Level IV (Supplement I) violation and applies to both Units.
