NPF-29 During an NRC inspection conducted on August 3 through September 6,1997, three violations of NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violations are listed below:
A.
Technical Specification 5.4.1.a requires, in part, that the licensee implement the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A,1978. Regulatory Guide 1.33, Appendix A, Section 4.w.(2)(a) recommends procedures for the operation of diesel generators.
Proceduw 04101 P81-1, "High Pressure Core Spray Diesel Generator,"
Revision 41, and Procedure 04-1-01-P751, " Standby Diesel Generator System,"
Revision 47, implemented this requirement. Procedure 04-1-01-P81 1, Section 4.1.2,d.(7) and Procedure 04-1-01-P751, Section 4.8.2.e, require verification that all fuel oil duplex strainers and filters are selected to one strainer / filter at a time.
Contrary to the above, as of August 11,1997, the duplex filter selection levers for the High Pressure Core Spray and the Division 1 Standby Diesel Generators, were in the "Both" position such that two strainers / filters were selected.
This is a Severity Level IV violation (Supplement I) (50-416/9719 01).
8.
10 CFR 50, Appendix B, Criterion Ill, requires tnat measures shall be established to assure that applicable regulatory requirements and the design basis for those structures, systems, and components are correctly translated into specifications, drawings, procedures, and instructions. The design control measures shall also provide for verifying or checking the adequacy of design, such as by the use of alternate or simplified calcuiational methods, or by the performance of a suitable testing program. Design changes, including field changes, shall be subiect to design control measures commensurate with those applied to the original design.
Contrary to the above, as of August 22,1997, design control measures had not assured that the battery racks were returned to the suismically tested configuration after the batteries were replaced in both divisions in accordance with Design Change Package 91/0112, Revision 0, in April and May 1992.
This is a Severity Level IV violation (Supplement 11(50-416/9719-03).

2 Updated Final Safety Analysis Report Section 8.1.4.4.1 requires that cable separation be maintained in accordance with Regulatory Guide 1.75 (January 1975), " Physical Independence of Electrical Systems."
Regulatory Guide 1.75 states that IEEE Std 3841974, " Criteria for Separation of Class IE Equipment and Circuits," sets forth criteria for separation of circuits and equipment that are redundant.
IEEE Std 3841974 requires that Non-Class 1E circuits be separated from Class 1E circuits by the minimum separation requirements or becomo associated circuits.
Contrary to the above, as of August 21,1997, the licensee had no procedure to control the installation of extension cords to ensure that the required separation from safety-related cable was maintained.
This is a Severity Level IV violation (Supplement I ) (50-416/9719 04).
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, D.C. 20555 with a copy to the Regional Administrator, Region IV,611 Ryan Plaza Drive, Suite 400, Arlington, Texas 76011, and a copy to the NRC Resident inspector at the facility that is toe subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation (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. Your response may reference or include previous docketed correspondence, if the correspondence adequately addresses the required response, if an adequate reply is not received within the time specified in this Notice, an order or a 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.
Because your response will be placed in the NRC Public Document Room (PDR), to the extent possible, it should not include any personal privacy, proprietary, or safeguards information so that it can be placed in the PDR without redaction. However, if you find it necessary to include such information, you should clearly indicate the specific information that you desire not to be placed in the POR and provide the legal basis to support your request for withholding the information from the public.
Dated at Arlington, Texas this 12th day of September 1997
