Commonwealth Edison Company Docket Nos.
50-254; 50-265 Quad Cities Station, Units 1 and 2 License Nos. DPR-29; DPR-30 During an NRC inspection conducted on April 6 through May 17, 1993, a violation of NRC requirements was identified.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1993), the violation-is listed below:
10 CFR 50, Appendix B, Criteria V states, in part, that activities affecting quality shall be prescribed by documented instruction of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions.
Contrary to the above, on March 31, 1993, during installation of emergency core cooling system (ECCS) room drain line strainers, a temporary alteration for installation of pipe plugs in place of floor drain check valves was not performed prior to removal of the drain line check valves. As a result, the affected ECCS components were made inoperable due to loss of flood protection.
This is a Severity Level IV violation (Supplement 1).
Pursuant to the provisions of 10 CFR 2.201, Commonwealth Edison is hereby required to submit a written statement of explanation to the U.S. Nuclear Regulatory Commission, ATIN: Document Control Desk, Washington D.C. 20555 with a copy to the U.S. Nuclear Regulatory Commission, Region III, 799 Roosevelt Road, Glen Ellyn, Illinois, 60137, and a copy to the NRC Resident Inspector at the Quad Cities Nuclear Station 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.
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 action as may be proper should not be taken. Where good cause is shown, consideration will be given to extending the response time.
