ENCLOSURE NOTICE OF 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 Nuclear Regulatory Commission (NRC) inspection conducted on June 21 -

August 20, 1986, violations of NRC requirements were identified. The violations involved a failure to control motor-operated valve design, a failure to establish an adequate surveillance procedure, and a failure to maintain Technical Specifi-cation (TS) operability requirements. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C

~

(1985), the violation is' listed below:

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

Appendix A of RG 1.33, Revision 2, specifies that activities involving reactor protection system tests and calibrations be performed in accordance with written procedures.

Contrary to the above, the procedure for Response Time Testing of Reactor Trip Breakers RTA and/or BYB (PT/0/A/4601/07A) was demonstrated to be inadequate in that it incorrectly allowed the opening of both the main reactor trip breaker and the bypass reactor trip breaker without requiring control room personnel to block the feedwater isolation signal. This resulte'd in an inadvertent actuation of the Unit 2 engineered safeguard features train A feedwater isolation' logic during a performance of the PT on June 23, 1986.

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

Pursuant to the provisions 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 written statement or explanation in reply including: (1) admission or denial of the violations, (2) the reason for the violations if admitted, (3) the corrective steps which have been taken and the results achieved, (4) the corrective steps which will be taken to avoid further viciations, and (5) the date when full compliance will *ae achieved. Where good cause is shown, con-sideration vill be given to extending the response time.
