l NOTICE OF VIOLATION Commonwealth Edison Company Docket No. 50-295;50 304 Zion Nuclear Power Plant License No: DPR-39; DPR 48 -

During an NRC inspection conducted on April 9 through July 30,1997, 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 below:

1, 10 CFR Part 50, Appendix B, Criterion XV, requires, in part, that measures shall be established to cr irol materials, parts, or components which do not conform to requirements in order to prevent their inadvertent use or installation. These measures shall include, as appropriate, procedures for identification, documentation, segregation, and disposition.

Contrary to the above, the Zion Station measures to control materials were inadequate and did not prevent installation of the following:

a.

From about 1992 to 1997, high efficiency particulate air (HEPA) filters containing aluminum in excess of the design basis limits, were installed inside Units 1 and 2 containments, ,

b. In February and April 199'7, nonseismically qualified starting solenoids were installed in the starting circuitry of the 1C and 2C diesel containment spray pumps, respective *y.

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

2. 10 CFR Part 50, Appendix B, Criterion XVI, requires, in part, that measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, and nonconformances are promptly identified and corrected. In the cases of significant conditions adverse to quality, the measure shall ensure that the cause of the condition is determined and corrective action taken to preclude repetition.

Contrary to the above,

a. From 1991 to 1997, the licensee's engineering design process failed to update operating procedura ECA 0.0, Revision 23," Loss of All AC Power," to include various DC loads that must be shed off the bus, under certain design basis conditions, as determined by design calculation 22S-B-007E-001,"125Vdc Battery Load Profile Analysis". The potential to operate the plant beyond the battery design basis existed.

b. From 1992 to 1997, the licensee failed to disposition four operability evaluation compensatory actions that allowed operation of the component cooling system down to 40*F. The licensee used this evaluation to justify operating below the 70'F limit identified in the precautions of the system operating procedure.

This is a beverity Level IV violation (Supplement I).

Pursuant to the provisions of 10 CFR 2.201, Comed is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, A1TN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region ill, 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 the Notice of Violation (Notice).

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 Demand for Information may be issued as to why the license should not be modified, suspended, or revoked, or why such other p action as may be proper should not be taken. Where good cause is shown, consideration will ~
