l NOTICE OF VIOLATION l

Commonwealth Edison Company Docket Nos, 50-295 l Zion Nuclear Generating Station License Nos. DPR-39 1

During an NRC inspection conducted on March 11 through April 25,1997, two 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 i below:

l

1. Technical Specification 6.2.1.a requires that written procedures be prepared, implemented, and maintained for procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.

Appendix A of Regulatory Guide 1.33, Revision 2, February 1978, specifies loss of ,

electric power (and/or degraded power sources) as an example of a procedure for l responding to an emergency or other significant event.

I Contrary to the above, on March 11,1997, the licensee identified that a procedure '

did not exist for responding to a loss of offsite power that resulted when the Unit 1  !

system auxiliary transformer tripped. '

This is a Severity Level IV Violation (Supplement I).

(50-295/97012-01)

2. 10 CFR Part 50, Appendix B, Criterion XVI, " Corrective Actions," requires that measures be established to assure that conditions adverse to quality are promptly identified and corrected, and in the case of significant conditions adverse to quality, that measures be established to assure that the cause of the condition is determined and corrective action taken to preclude recurrence.

Contrary to the above, frem January 20,1996, through March 11,1997, the licensee did not implement timely and effective corrective actions to prevent the recurrence of sequence timer malfunctions, a condition adverse to quality.

Specifically, the corrective actions specified in the licensee's level 2 root cause investigation, Nuclear Tracking System No. 295-200-96-CAT 2-003, for recurring sequence timer malfunctions, were not completed prior to the failure of the division 17-2 safe shutdown timer to reset on March 11,1997.

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

(50-295/97012-02)

Pursuant to the provisions of 10 CFR 2.201, Cornmonwealth Edison Company 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 lil, and a copy *o the NRC Resident inspector at the facility I that is the subject of this Notice, within 30 day of the date of the letter transmitting this l Notice of Violation (Notice).

contested, the basis for disputing the violation, (2) the corrective steps that have been l,

taken and the results achieved, (3) the corrective steps that will be taken to avoid further violatiors, and (4) the date when full compliance will be achieved. Your response may reference or include previous docketed correspondence, if the correspondence adequately addiesses the required response. If an adequate reply is not received within the time specified in the Notice, an order or a Demand for Information may be issued as to why the l

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 responso 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, if personal privacy or proprietary information is necessary to provide an acceptable response, then please provide a bracketed copy of your response that identifies the information that should be protected and a redacted copy of your response that deletes such information. If you request withholding of such material, you must specifically identify the portions of your response that you seek to have withheld and provide in detail the bases for your claim of withholding (e.g., explain why the disclosure of information will create an unwarranted invasion of privacy or provide the information required by 10 CFR 2.790(b) to support a request for withholding confidential commercial or financialinformation), if safeguards information is necessary to provide an acceptable response, please provide the level of protection described in 10 CFR 73.21.
