3/4.8 ELECTRICAL POWER SYSTEMS BASES l The OPERABILITY of the A.C. and D.C. power sources and associated distribution systems during operation ensures that sufficient power will be available to supply the safety related equipment required for 1) the safe shutdown of the facility and 2) the mitigation and control of l accident conditions within the facility. The minimum specified indepen-

! dent and redundant A.C. and 0.C. power sources and distribution systems satisfy the requirements of General Design Criteria 17 of Appendix "A" to 10 CFR 50.

The ACTION requirements specified for the levels of degradation of' the power sources provide restriction upon continued facility operation commensurate with the level of degradation. The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least one of each of the onsite A.C. and D.C. power sources and associated distribution systems OPF.RABLE during accident conditions coincident with an assumed loss of offsite power and sing 1c failure of the other onsite A.C. source.

l The OPERABILITY of the minimum specified A.C. and D.C. power sources an'd associated distribution systems during shutdown and refueling ensures that 1) the facility can be maintained in the shutdown or refueling condition for extended time periods and 2) sufficient instrumentation and control capability is available for monitoring and maintaining the facility status.

The basis for depressurizing and venting the RCS through a

>3.40 square-inch vent when less than the required busses are OPERABLE is provided on Page B 3/4 4-9.
