s ENCLOSURE 1 NOTICE OF VIOLATION Entergy Operations, Inc.

Docket No.:

50-416 Grand Gulf License No.:

NPF-29 During the Nuclear Regulatory Commission (NRC) inspection conducted on August 15 through September 18, 1993, a violation of NRC requirements was identified.

In accordance with the " General 5tatement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violation is listed below:

Technical Specification 6.8.1.c requires that written procedures be established, implemented, and maintained covering the applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33, Revision 2.

Regulatory Guide 1.33 recommends that procedures for performing maintenance which can affect the performance of safety related equipment should be properly preplanned and performed in accordance with written procedures and documented instructions.

General Maintenance Instruction 07-S-13-60, Reactor Vessel Reference leg Purge, provides instructions for purging reference legs of noncondensible gases.

Contrary to the above, Instruction 07-S-13-60 was inadequate in that it did not adequately address the setpoint of slaved trip units which caused an unplanned Reactor Core Isolation Cooling injection on September 14, 1993.

This is a Severity Level IV violation (Supplement 1).

Pursuant to the provisions of 10 CFR 2.201, Entergy Operations, Inc. is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, Attn: Document Control Desk, Washington, DC 20555, with a copy to the Regional Administrator, Region II, and a copy to the NRC Resident Inspector, Grand Gulf Nuclear Station within 30 days of the date of the letter transmitting this Notice. This reply should be 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 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 extending the response time.
