' BASES The OPERABILITY'of the A.C. and D.C. power sources and associated distribu-
~
l
, tion' 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 accident conditions within the facility. The minimum specified independent and l
1 redundant A.C. and D.C. power sources and distribution systems satisfy the requirements-of General Design Criterion 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 safety analyses and are based upon maintaining at least one of each of the onsite A.C.~and 9.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss of offsite power and single failure of the other onsite A.C. source.
The OPERABILITY of the minimum specified A.C. and D.C. power sources and-associated distribution systems during shutdown and refueling ensures that
- 1) the' facility can be maintained in the shutdown or refueling condition i
"for extended tide periods and 2) sufficient instrumentation and control capability is available for monitoring and maintaining the facility status.
l The Surveillance Requirements for demenstrating the OPERABILITY of the station batteries are based on the recommendations of Regulatory Guide 1.129, " Maintenance Testing and Replacement of Large Lead Storage Batteries
_ for Nuclear Power Plants", February 1978, and IEEE Std. 450-1980, "IEEE Recommended Practice for Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations".
Verifying average electrolyte temperature above the minimum for which the battery was: sized,. total battery terminal voltage on floa.t charge, connec-tion resistance values and the performance of battery service and discharge
~
tests ensures the effectiveness of the charging system, the ability to i
handle high discharge rates and compares the battery capacity at that time with the rated cepacity.
4 Table 4~.8-1 specifies the normal limits for each designated pilot cell and each connected cell for electrolyte level, float voltage and specific gravity. The limits for the designated pilot cells float voltage and 4
specific gravity, greater than 2.13 volts and.015 below the manufacturer's full charge specific gravity is characteristic of a charged cell with 4
adequate capacity. The normal limits for each connected cell for float voltage and specific gravity, greater than 2.13 volts and not more than
.020 below the manufacturer's full charge specific gravity with an average specific gravity of all the connected cells not more than.010 below the manufacturer's full charge specific gravity, ensures the OPERABILITY and cape.bility of the battery.
