APPENDIX A NOTICE OF VIOLATION Docket Nos. 50-277 Philadelphia Electric Company 50-278 Peach Bottom Units 2 and 3 License Nos. DPR-44 DPR-56 i
As a result of the inspection conducted on January 25 through February 12,1993, and in i
accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (Enforcement Policy) (1992), the following violation was identified:
10 CFR 50, Appendix B, criterion states, in part, that "A test program shall be established to assure that all testing required to demonstrate that structures, systems, and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the requirements and j
acceptance limits contained in applicable design documents. The test program shall include, as appropriate, proof tests prior to installation, preoperational tests, and operational tests during nuclear power plant or fuel reprocessing plant operation, of structures, systems, and components."
Contrary to the above, on February 12, 1993, Peach Bottom did not have test programs for the molded case circuit breakers and Topaz inverters to periodically demonstrate that 1) the breakers would trip within the design current band, and 2) the inverters would trip when the input voltage exceeded the design limit of 100 Vdc and 147 Vdc. Most of the molded case circuit breakers and the Topaz inverters had not j
been tested since starting commercial operation about twenty years ago.
1 This is a Severity Level IV Violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, the Philadelphia Electric Company is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, A'ITN: Document Control Desk, Washington, D.C. 20555, with a copy to the Regional Administrator, Region I, and a copy to the NRC Resident Inspector within 30 days of the date of the letter transmitting this Notice of Violation. This reply should include:
l (1) the reason for the violation, if admitted, 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 violation, and (4) the date when full compliance will be achieved.
