ENCLOSURE 1 NOTICE OF VIOLATION Wolf Creek Nuclear Operating Corporation Docket No.: 50-482 Wolf Creek Generating Station License No.: NPF-42 During an NRC inspection conducted on October 7-11 and 21-25,1996, three violations of NRC equirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600,the violations are listed below:

A. 10 CFR 50, Appendix B, Criterion Ill, requires, in part, that measures be established to assure that regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures, and instructions. These measures shall include provisions to assure that appropriate quality standards are specified and included in design documents.

Contrary to the above, on October 18,1996, the design basis was not correctly l

translated into specifications for Configuration Change Package 07111, Revision 1, which was approved with an incorrect assumed essential service water flow rate.

Specifically, the basis for the suitability of the containment air coolers with reduced heat removal capacity used calculations with an assumed essential service water flow rate of 4000 gpm rather than the actual flow rate of 2000 gpm available to the coolers.

This is a Severity Level IV violation (Supplement I) (50-482/96021-01).

B. Criterion V of Appendix B to 10 CFR Part 50 requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, and drawings appropriate to the circumstances, and shall be accomplished in accordance with these instructions, procedures, or drawings.

Procedure ADM O2-024," Technical Specification Operability," requires operability

determinations to include a determination of the requirement or commitment established for the equipment.

Contrary to the above, on October 22,1996, at 2:10 pm, the shift supervisor reviewed a statement that listed conflicting Updated Safety Analysis Report, Technical Specification and Calculation GN-MW-005 information, which pertained to containment air cooler essential service water flow rates, and performed an operability determination without including the requirement established for the equipment. Specifically, the shift supervisor relied on an out-of-date Calculation GN-MW-005, which assumed a cooler group (i.e., two coolers) flow rate of 4000 gpm, instead of determining the actual requirement for containment air cooler group essential service water flow rate of 2000 gpm.

This is a Severity Level IV violation (Supplement 1)(50-482/96021-05).

C. Technical Specification 6.8.1.a states, in part, that written procedures shall be established, implemented and maintained, covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2.

Regulatory Guide 1.33, Appendix A, Section 3.n, requires procedures for startup, operation, and shutdown of the chemical and volume control system.

Procedure STS BG-004, "CVCS Seal Injection and Return Flow Balance,"

Revision 4, provides procedural guidance for setting the positions of sealinjaction throttle valves BGV-198, BGV-199, BGV-200, and BGV-201, and performing Technical Specification Surveillance Requirement 4.5.2.g (verifying the correct position of mechanical position stops) for these valves.

Contrary to the above, on October 23,1996, Procedure STS BG-004 did not specifically require operators to tighten or verify the mechanical position stops for valves BGV-198, BGV-199, BGV-200, and BGV-201.

This is a Severity Level IV violation (SupplemeniI) (50-482/96021-06).

Pursuant to the provisions of 10 CFR 2.201, Wolf Creek Nuclear Operating Corporation 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 Regions! 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 the subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be clear;v 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 wi!! 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 correpondence 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 acten as may be proper should not be taken. Where good cause is shown, consideration will t,e given to extending the response time.

Because the response will be placed in the NRC Public Document Room, to the extent possible, it should not include any personal privacy, proprietary, or safeguards inbrmation so that it can be placed in the Public Document Room without redaction. However, if it is necessary to include such information, it should clearly indicate the specific information that should not be placed in the Public Document Room, and provide the legal basis to support the request for withholding the information from the public.

Dated at Arlington, Texas this 31st day of December,1996
