NOTICE VIOLATION Duke Power Company Docket Nos. 50-369 and 50-370 McGuire Units 1 and 2 License Nos. NPF-9 and NPF-17 During the Nuc! ear Regulatory Comission (NRC) inspection conducted on December 30, 1986, to February 10, 1987, two violations of NRC requirements were identified. Both violations involved failures to comply with Technical Specification (TS) 6.8.1. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1985),

the violations are identified telow:

A. Technical Specification 6.8.1.a requires that current written approved procedures, be established implemented and maintained covering reactor startup and safety related equipment operation.

Operations Management Procedure 2.5, section 6.6, requires that the operator ensure redundant equipment is operable prior to removing equipment from service.

Contrary to the above, on December 30, 1986, train 'B' of containment spray and train ' A' of the solid state protection system (SSPS) were removed from service simultaneously. Thus, both trains of containment spray were removed from service simultaneously.

This is a Severity Level IV (Supplemer.t I) violation and applies to Unit 1 only. This violation is similar to a violation cited in NRC Inspection Report Nos. 50-369/86-08 and 50-370/86-08.

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

RG 1.33, Revision 2, February 1978 recommends that general plant operating procedures be developed to govern preparation for refueling and refueling equipment operation. Procedures for the startup, operation, and shutdown of containment systems are also recommended.

Contrary to +he above, the general plant / containment system operating procedures proved to be inadequate, in that they failed to establish administrative controls to govern the re.Nyal and reinstallation of curbing sections designed to minimize the influx of water into the containment air return fans during a loss of coolant accident requiring the actuation of the containment spray system. The removable curb sections had been taken out of both units' containment buildings during a previous refueling outage and were discovered missing on January 30, 1987.

This is a Severity Level IV (Supplement I) violation.

Pursuant to the previsions of 10 CFR 2.201, Duke Power Company is hereby required to submit to this Office within 30 days of the date of the letter transmitting this Notice a writter statemer.t or explanation in reply including

Where good cause is shown, consideration will be given to extendir.g the response time.
