APPENDIX A NOTICE OF VIOLATION Philadelphia Electric Company Docket Nos. 50-352 Limerick Generating Station, Units 1 and 2 50-353 License Nos. NPF-39 NPF 85 As a result of the inspection conducted on August 31 through October 9,1992, and in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (Enforcement Policy) (1992), the following violations were identified:

A. 10 CFR 50, Appendix B, Criterion XI, requires, in part, that "A test program shall be established to assure that all testing required to demonstrate that structures, systems, and component:. will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the requirements and acceptance limits contained in applicable design documents. Test results shall be documented and evaluated to assure that test requirements have been satisfied."

Contrary to the above, the design requirements and acceptance limits were not properly translated into test procedures, in that:

1. On and before October 2,1992, the additional Class IE batteries loads shown on calculation No. 6600 E.22, Revision 1, calculation No. 6600 E.09, Revision 4A, Appendix IX, and for the HPCI pump discharge valve were not incorporated into the surveillance procedures, Technical Specifications and FSAR.

2. On and before October 2,1992, the design requirement for a minimum battery voltage of 108 Vdc stated in design calculation No. 6470 E.26, Revision 3, was not incorporated in the Technical Specification surveillance test procedures. The existing surveillance test procedures used a less conservative value of 105-Vdc to demonstrate that 125/250 Vdc batteries will perform satisfactorily in service.

3. On September 29,1992, the test technician failed to notify the shift supervisor immediately when the as-found time delay of 12 seconds was measured for the 93% degraded voltage with simulated LOCA signal present. This value exceeded the Technical Specifications limit of 11 seconds.

These items collectively constitute a Severity Level IV violation (Supplement I).
