NOTICE OF VIOLATION I Commonwealth Edison Company Dockets No. 50-373; 50-374

LaSalle County Station Units 1 and 2 Licenses No. NPF-11, NPF-18 During an NRC inspection conducted on August 3, through September 13, 1996, a violation of NRC requirements was identified. In accordance with the " General

, Statement'of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violation is listed below:

l 10 CFR 50, Appendix B, Criterion V, requires, in part, that activities

affecting quality shall be prescribed by documented instructions, procedures,  ;

! or drawings, of a type appropriate to the circumstances and shall be j accomplished with these instructions, procedures, or drawings.

LaSalle Technical Procedure (LTP)-500-1, " Diesel Generator Output Breaker Troubleshooting Procedure," Revision 6, stated, in part, that the purpose of the procedure is to determine the failure mode in the event that a diesel

, generator (DG) output breaker fails to close during its monthly operability 1

surveillance.

Contrary to the above, on August 14, 1996, the output breaker for the "0" DG failed, but LTP-500-1 was not used to troubleshoot and determine the failure mechanism.

This is a Severity Level IV Violation (Supplement I). l Pursuant to the provisions of 10 CFR 2.201, Comed is hereby required to submit a written statement of explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555 with a copy to the Regional Administrator, Region III, and a copy to the NRC Resident Inspector at the  :

LaSalle facility, within 30 days of the date of the letter transmitting this l 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 i 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 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 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.
