NOTICE OF VIOLATION Duke Power Company Docket No. 50-414 Catawba Unit 2 License No. NPF-52 EA 89-138 During the Nuclear Regulatory Commission (NRC) inspection conducted on-June 16 - June 28, 1989, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforce-ment Actions," 10 CFR Part 2, Appendix C (1989), the violation is listed below:

Technical Specification 3.3.3.6 requires that the accident monitoring channels as shown in Table 3.3-10 be operable in Modes 1, 2 and 3. Action Statement b. specifies that with the number of operable accident monitor-ing instrumentation channels less than the minimum channels operable requirements of Table 3.3-10, restore the inoperable channels to operable status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or be in at least hot standby within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. Table 3.3-10 shows the total number of channels required for Reactor Vessel Water Level as 2 and the minimum number of channels opera-ble as 1.

Contrary to the above, both channels of Unit 2 Reactor Vessel Water Level instrumentation were inoperable from June 2,1989 to June 16, 1989, with the reactor in Modes 1, 2, and 3, and the licensee failed to comply with the action statement. The channels were inoperable because the isolation valves for the upper range pressure transmitters were closed on both channels.

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

Pursuant to the provisions of 10 CFR 2.201, Duke Power Company is hereby required to submit a written statement or explanation to the Director, Office i of Enforcement, U.S. Nuclear Regulatory Commission, within 30 days of the date of this Notice. This reply should be clearly marked as a " Reply to a Notice of Violation" and should include: (1) admission or denial of the violation, (2) the reasons for the violation if admitted, (3) the corrective steps that have been taken and the results achieved, (4) the corrective steps which will be taken to avoid further violations, and (5) the date when full compliance will be achieved. If an adequate reply is not received within the time speci-fied in this Notice, an order may be issued to show cause why the license should not be modified, suspended, or revoked or why such other action as may be proper should not be taken. Consideration may be given to extending the response time for good cause shown. Under the authority of Section 182 of the Act, 42 U.S.C. 2232, this response shall be submitted under oath or affirmation.
