APPENDIX A NOTICE OF VIOLATION Wolf Creek Nuclear Operating Corporation Docket: 50-482 Wolf Creek Generating Station License: NPF-42 During an NRC inspection conducted June 1-30, 1990, two violations of NRC requirements were identified. The violations involved two examples of inadequate corrective actions and failure to follow a procedure. In accordance  :

with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1990) (Enforcement Policy), the violations are listed below: ,

A. Inadequate Corrective Action Criterion XVI of 10 CFR 50, Appendix B, corrective actions, requires, in part, that measures shall assure that the cause of the condition is t determined and corrective action taken to preclude repetition.

The licensee event report (LER) system described in 10 CFR 50.73, and the licensee's Administrative Procedure ADM-01-033 Revision 21, " Instructions t Describing Reportability Review and Documentation of Licensee Event ,

Reports (LERs) and Defects / Deficiencies," paragraph 5.2.7, requires that an LER describe any corrective actions planned as a result of the event, including those to reduce the probability of similar events occurring in the future.

Contrary to the above, the corrective action specified in LER 90-004, for 1 failure to satisfy a Technical Specification (TS) requirement because of personnel error in scheduling a surveillance test, was not appropriate to reduce the probability of similar events occuring in the future. The corrective action specified in LER 90-004 was similar to corrective action taken in LER 87-014 to procedually require the review of the past due ,

surveillance test report on a weekly basis. This previous corrective  !

action failed to prevent similar events in LERS89-016 and 90-004 from "

recurring. I In addition, the corrective action specified in LER 90-010, for inoperability of two auxiliary feedwater pumps because of a failure to communicate troubleshooting activities on a support system to the licensed operators, was not sufficient to prevent a similar event from occuring within the next 6 weeks. On June 18, 1990, the control room operators were not adequately informed about troubleshooting activities on the digital rod position indication system. As a result, several simultaneous alarms and indicators were received in the control room which were not expected by the operators.

This is a Severity Level IV violation. (Supplement I) (482/9026-01) 9008060299 9G0731 PDR ADOCK 05000482 Q FDC

L' ,

2 B. Failure to Follow Procedure TS require that written procedures shall be established, implemented, and maintained covering those activities recommended in Appendix A of Regulatory Guide (RG) 1.33. Revision 2 February 1978. RG 1.33 requires, in part, that there be administrative procedures covering the authorities and responsibilities for safe operation and shutdown.

Procedure ADM 02-400, Revision 7, "Posttrip Review," Section 6.5.1 states that strip-chart recordings must accurately reflect real time to have meaningful information. Section 6.12.1 requires that the actual or suspected cause of the trip and any abnormal or degraded indication identified during the transient shall be documented in Part 6 of the posttrip review report. Sections 5 1.1 and 1.2 state that the posttrip review will permit a determination to be made as to the readiness of the plant to safely restart.

Contrar to the above, the strip charts included in the posttrip reviews for H? 4, 17, and 19, 1990, did not reflect real time; Part 6 of the poi review for May 14, 1990, was not completed; and the posttrip rev ,or May 17, 1990, did not completely document corrective actions takse, or efforts taken to look for other contributing causes.

This is a Severity Level IV violation. (Supplement 1) (482/9026-02)

Pursuant to the provisions of 10 CFR 2,201, Wolf Creek Nuclear Operating Corporation is hereby required to submit to this office, within 30 days of the date of the letter transmitting this Notice, a written statement or explanation in reply, including for each violation: (1) the reason for the violation if admitted, (2) the corrective steps which have been taken and the results achieved, (3) the corrective steps which will be taken to avoid further violations, and (4) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending the response time.

Dated at Arlington, Texas, this 3/g day of /d 1990 y
