ENCLOSURE 1 NOTICE OF VIOLATION Duke Power Company Docket Nos. 50-269, 270, and 287 Oconee.1, 2, and 3 License Nos. DPR-38, 47 and 55 During an NRC inspection conducted on January 31 - February 27, 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, the violation is listed below:
Oconee Technical Specification (TS) 6.4.1 requires that the station be operated and maintained in accordance with approved procedures with appropriate instructions for conditions involving nuclear safety-related periodic test procedures.
Contrary to the above, Performance Test (PT) Procedure, PT/1/A/610/06, 100 KV Power Supply.From Lee Steam Station, revised September 3, 1991, was inadequate in that it did not address an abnormal condition involving both the switchyard battery chargers being fed from a single source (1TE).
Consequently, on January 26, 1993, during the performance of the PT, both battery chargers supplying the 230 KV Switchyard 125 VDC System were deenergized for forty minutes, making both battery chargers inoperable. Both battery chargers are required to be operable per TS 3.7.1.(g).
The loss of both chargers resulted in battery discharge down to approximately 121 VDC from a nominal voltage of approximately 135 VDC and below the TS 4.6.9 required minimum voltage of 125 VDC.
This is a Severity Level IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Duke Power 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 II, 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 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 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, considerationwill be given to extending the response time.
