ENCLOSURE 1 NOTICE OF VIOLATION Carolina Power and Light Company Shearon Harris Unit 1

Docket No. 50-400 License No.

NPF-63 During an NRC inspection conducted on February 23 - March 22, 1991, 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 (1991), the violation is listed below:

Technical Specification 3.3.1 requires that Reactor Trip System instrumentation channels and interlocks of Table 3.3-1 shall be operable.

Table 3.3-1, item 16, requires two reactor coolant pump underfrequency trip channels per reactor coolant pump.

Contrary to the above, from approximately November 29, 1990, until March 5,

1991, two reactor coolant pump underfrequency trip channels were not available for the "A" and "C" reactor coolant pumps.

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

Pursuant to the provisions of 10 CFR 2.201, Carolina Power and Light Company is hereby required to submit a written statement or 'explanation to the U.S.

Nuclear Regulatory Commission, ATTN:

If an adequate reply is not received within the time specified 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.

Where good cause is shown, consideration will be given to extending the response time;-"
