ENCLOSURE 1 NOTICE OF VIOLATION Duke Power Company Docket Nos. 50-369, 50-370 McGuire Units 1 and 2 License Nos. NPF-9, NPF-17 During the Nuclear Regulatory Commission (NRC) inspection conducted on~ May 22,.

1990 through June' 25,1990, a violation of NRC requirements was identified.

In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1990), the violation is identified below:

A. Technical Specification (TS) 3.7.6 requires two' independent Control Room Ventilation-(VC) Systems to be operable at all times. If both trains of VC are inoperable the licensee is required to enter TS_3.0.3 which requires that within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> action shall be initiated to place the unit in a MODE in which the specification does not apply by placing it, as applicable -in:

1. At least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />,

2. At least HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and 3.. At least COLD SHUTDOWN within the subsequent 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />..

TS 4.7.6.e.3 requires that'VC be able to maintain a' positive pressure in the Control Room of greater than or equal to 1/8-inch water gauge relative to outside atmosphere.

Contrary to the above, the licensee operated both Units at Power Operation with two of four VC intakes closed from May 25, 1990 until June 3, 1990 rendering both VC trains inoperable. i.e. unable to meet the TS required pressurization criteria.

This is a Severity Level IV Violation (Supplement 1)

B. 10 CFR 50.72 (b) (iii) (d) requires that the licensee report to NRC within-4-hours any. event or condition that alone could have prevented the ful-fillment of the safety function of systems that are needed to mitigate the consequences of an accident.

Contrary to the above, the licensee discovered an inoparability of both trains of the Control Room Ventilation System at 10:? p.m. on June 3, 1990 but did not report the event to NRC until 5:30 p.w. on June 4,1990.

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