ENCLOSURE 1 NOTICE OF VIOLATION Duke Power Company Docket Nos. 50-369 and 50-370 McGuire Unit 1 and 2 License Nos. NPF-9 and NPF-17 During the Nuclear Regulatory Commission (NRC) inspection conducted on June 25, 1988 through July 22, 1988, violations of NRC requirements were identified. In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1988), the violations are identified below:

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

Regulatory Guide 1.33, Revision 2 February 1978, Appendix A, requires that procedures be written, implemented, and maintained for energizing, filling, draining, startup, shutdown, and changing modes of operation of safety related systems.

McGuire procedure OP/2/A/6350/05, AC Electrical Operation Other Than Normal Lineup, specifies the method to be used to align 6900 volt switch gear assemblies to their alternate power supply.

McGuire procedure OP/2/A/6250/03A, Steam Generator Cold Wet Layup Recirculation, specifies the method to be used to drain and refill steam generators.

McGuire Operations Management Procedure 2-17, Tagout/ Removal and Restoration (R&R) Procedure, states in part that the purpose of a Tagout (R&R) Record Sheet is to allow the removal and restoration of equipment to be accomplished in a specific manner by directing the sequence of the steps involved in repositioning the equipment and indicating the desired removal and return position.

Tagout R&R Number 28-616, Tagout for Busline 2B, specified the method to be used to realign the off site electric power supply to Unit 2 to allow maintenance on busline 28.

1. Contrary to the above, procedure OP/2/A/6250/03A, Steam Generator Cold Wet Lay up Recirculation, was inadequate in that performance of the procedure caused an Engineered Safety Features actuation. The procedure failed to block the auto start signal to the turbine driven auxiliary feedwater pump on low-low level in two steam generators, i

2. Contrary to the above, procedure OP/2/A/6350/05, AC Electrical Operation Other Than Normal Lineup, was not properly implemented in that an incorrect electrical lineup of the Unit 2 6900 volt switch gear assemblies was made on June 24, 1988 which resulted in a loss of all Unit 2 off site power. In preparation for maintenance on the 28 off site busline, a reactor operator incori-ectly aligned all four 6900 voit switch gear assemblies to the 2B off site busline instead of the 2A offsite busline as intended by the procedure. When the 2B busline was subsequently removed from service, a loss of all off site power occurred, causing an Engineered Safety Features actuation.

3. Contrary to the above, Removal and Restoration (R&R) procedure 28-616. Tagout for Busline 2B, was inadequate in -that it did not direct the sequence of steps required to operate the 2B busline Primary Circuit Breakers when the 28 off site busline was remcVed from service on June 24, 1988.

This is a Severity Level IV (Supplement I) violation and applies to Unit 2.

B. Technical Specification 6.2.3.3 requires that the Station Safety Review Group maintain surveillance of plant activities to provide independent verification that these activities are performed correctly and that human errors are reduced as much as possible.

Contrary to the above, a review of McGuire Safety Review Group (MSRG) activities covering the period of 1986 through June 1988 revealed that the MSRG did not perform routine independent surveillance of plant operations and maintenance cetivities to provide indeperdent verification that these activities were performed correctly.

This is a Severity Level IV (Supplement I) violation and applies to both units. i Pursuant to the provisions of 10 CFR 2.201, Duke power Company is hereby requ', red to submit a written statement or explanation to the U.S. Nuclear j Regulatory Commission, ATTN; Document Control Desk, Washington, DC 20555 with a copy to the Regional Administrator, Region II, and a copv to the NRC Resident ,
