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 January 11 through February 22,1997, five  ;

violations of NRC requirements were identified. In accordance with the " General ,

Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the I violations are listed below:

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

Regulatory Guide 1.33, Appendix A, Section 1.h, requires administrative procedures I for log entries. l Administrative Procedure AP 21-001," Operations Watchstanding Practices,"

Revision 4, Step 6.2.3.d, requires a log entry for entry into Technical Specification action statements due to equipment failure. l l

Contrary to the above, on July 28,1996, at 5:15 p.m., the shift supervisor logged l a failure of Containment Isolation Valve EF HV0034 to close on demand, but failed to recognize that this valve f ailure resulted in entry into Technical Specification l Action Statement 3.6.3 and fciled to log entry into Technical Specification Action Statement 3.6.3.

This is a Severity Level IV violation (Supplement IV) (482/9704-01).

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

Regulatory Guide 1.33, Appendix A, Section 9, requires procedures for performing maintenance that can affect the performance of safety-related equipment.

Administrative Procedure AP 16C-002," Work Controls," Revision 4, Attachment C, Step C.2.1, requires workers to perform troubleshooting activities using a work package task with authorization from the shift supervisor.

System operating Procedure SYS AL-124, " Venting the Turbine-Driven Auxiliary Feedwater Pump Oil System," Step 6.1.4, requires operators to open Valve FC HV0312, a turbine-driven auxiliary feedwater pump trip-throttle valve, until the turbine operates between 3850 and 3900 rpm, then slowly open the valve while verifying that the governor valve maintains control of the turbine.

1 Contrary to the above, on January 24,1997, system engineers failed to comply with procedures for performing maintenance. Specifically:

1. The system engineer manipulated Valve FC FV0313, the turbine-driven auxiliary feedwater pump governor valve while troubleshooting an inadvertent overspeed trip without a work package task and without authorizstion from the shift supervisor.

2. Under the direction of the system engineer, control room operators man pulated the speed of the turbine-driven auxiliary feedwater pump to below 3850 rpm.

This is a Severity Level IV violation (Supplement IV) (482/9704-02).

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

Regulatory Guide 1.33, Appendix A, Section 9, requires procedures for performing maintenance, System operating Procedure SYS AL-124, " Venting the Turbine-Driven Auxiliary Feedwater Pump Oil System," Revision 1, provides guidance for postmaintenance testing of the turbine-driven auxiliary feedwater pump.

Contrary to the above, on January 24,1997, licensee personnel failed to properly establish Procedure SYS AL-124. Specifically:

1. The procedure contained a precaution to closely monitor the bearing o!!

pressure when operating the turbine at low speeds, but failed to define low speeds and low oil pressure and failed to specify what actions were to be taken when low oil pressure was reached.

2. On-The-Spot Change 97-0023 to the procedure required operators to manually open the trip-throttle valve and control turbine speed at approximately 2500 rpm. With the governor controller set at the normal position of approximately 3850 rpm, this could not be accomplished due to the design of the ramp generator circuit that attempted to accelerate the turbine from approximately 1100 rpm to the normal setting of the controller, 3850 rpm.

This ista Severity Level IV violation (Supplement IV) (482/9704-03).

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

V

3-Regulatory Guide 1.33, Appendix A, Section 3.1, requires procedures for operation of the auxiliary feedwater system.

System Operating Procedure SYS AL-124, " Venting the Turbine-Driven Auxiliary Feedwater Pump Oil System," Step 6.1.5, requires the operator to trip the turbine-driven auxiliary feedwater pump using the manual trip lever.

Contrary to the above, on January 24,1997, the operator unsuccessfully attempted to trip the turbine-driven auxiliary feedwater pump by pulling on the trip linkage, causing the turbine speed to increase.

This is a Severity Level IV violation (Supplement IV) (482/9704-04).

I E. 10 CFR 50.54(q) permits the licensee to make changes to the emergency plans without prior Commission approval only if the changes do not decrease the effectiveness of plans and meet the standards of 10 CFR 50.47(b).

Contrary to the above, on February 23,1996, the licensee changed the emergency ,

plan, which resulted in a decrease in the effectiveness of their plan without prior l NRC approvalin that an emergency action level form that would have previously classified a particular event as a site area emergency was changed to classify it as i an Alert.

This is a Severity Level IV violation (Supplement l} (482/9704-07).

l 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 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 the subject l 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 l 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

, -4 necessary to include such information, you should clearly indicate the specific information that you desire not to be placed in the PDR and provide the legal basis to support your request for withholding the information from the public.
