NOTICE OF VIOLATION Duke Power Company Docket No. 370 McGuire Unit 2 License No. NPF-17 i

i During an Nuclear Regulatory Commission (NRC) inspection conducted on March 14, 1993 through April 17 1993, 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, the violation is listed below:

10 CFR 50.72 (b)(2)(ii) requires that a licensee notify the NRC as soon 4

as practical and in all cases within four hours of the occurrence of any event or condition that results in a manual or automatic actuation of any engineered safety feature (ESF).

Contrary to the above, at 2:50 p.m. on March 22, 1993, a fitting on the i

Unit 2 Chemical and Volume Control System failed, causing a reactor i

coolant leak of approximately 75 gallons per minute.

A manual actuation of a second charging pump, an ESF pump, was initiated to control t

pressurizer level. The manual actuation was not reported to the NRC i

until 4:10 p.m. on March 23, 1993.

This is a Severity Level IV (Supplement 1) violation applicable to Unit 2 only.

Pursuant to the provisions of 10 CFR 2.201, Duke Power Company is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN:

Document Control Desk, Washington, D.C. 20555 i

with a copy to the Regional Administrator, Region II, a copy to the NRC I

Resident Inspector, at the McGuire facility within 30 days of the date of the j

letter transmitting this Notice of Violation (Notice). This reply should be t

clearly marked as a " Reply to a Notice of Violation" and should include for each violation:

(1) the reason for the violation, or, if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to avoid further violations, and (4) the date when full compliance will be achieved.

If an adequate reply is not received within the time specified in this Notice, an l

order or demand for information may be issued as to why the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken. Where good cause is shown, consideration will be given to 1

extending the response time.
