The OPERABILITY of the minimum specified A.C. and D.C. power sources and associateddistributionsystemsdurit,gshutdownandrefuelingensuresthat1) i 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.
1 The Surveillance Requirements for demonstrating the OPERABILITY of the station 4
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 IF.EE Std. 450-1980, "IEEE-Recommended Practice for Maintenance. Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations," exceat that certain tests will be performed at least once each REFUELING INTERVAL.
Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, connection resistance values and the performance of battery service and discharge tests-ensures the effectiveness of the charging system, the ability to handle high discharge rates and compares the battery ccpacity at that time with the rated-capacity.
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 specific gravity,
_ greater than 2.13 volts and.015 below the manufacturer's full charge specific gravity or a battery charger current of less than two amps is characteristic of a charged cell with adequate capacity. The normal limits for each connected cell for float voltage and specific grnityf greater than 2.13 volts and not more than.020 below the manufacturer's fuli charge specific gravity with an
- average specific gravity of all the counted cells not more than.010 below the mano acturer's full charge specift: gravity, ensures the OPERABILITY and ca) ability of the battery. Exceptions te the specific gravity requirements are-taten to allow-for the normal deviatio.A experienced after a battery discharge and' subsequent recharge associated with a service or performance discharge test. The specific gravity deviations are recognized and discussed in IEEE 450-1980.
