3/4.8 ' ELECTRICAL POWER SYSTEMS BASES-Surveillance Requirements 4.8.1.1.2.a.4 and 4.8.1.1.2.c.4 verify proper starting of the Emergency Diesel Generators from standby conditions.

Verification that an Emergency Diesel Generator has achieved a frequency of 60 Hz.within the required time constraints meets the requirement for verifying

. the Emergency Diesel Generator has accelerated to 900 RPM.

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 for extended time periods and 2) sufficient instrumentation and control capability is available. for monitoring and maintaining the facility status.

.The Surveillance Requirement:; for demonstrating 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. 450-1995, "IEEE Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead

- Acid Batteries for Stationary Applications," except that certain tests will be performed at least once each REFUELING INTERVAL.

Battery degradation is indicated when the battery capacity drops more than 10%

from its capacity on the previous performance discharge or modified performance discharge test, or is below 90% of the manufacturer's rated capacity.

Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, connection resistance values rnd the performance of battery service and discharge tests ensures the effecthposs of the charging system, the ability to handle high discharge rates and compares the battery capacity 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 cell's float voltagu and specific gravity, l

j 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 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 4

the manufacturer's full charge specific gravity, ensures the OPERABILITY and i

capability of the battery. Exceptions to the specific gravity requirements are taken to allow for the normal deviations experienced after a battery discharge and subsequent recharge associated with a service, performance discharge, or

. modified performance discharge test. The specific gravity deviations are recognized and discussed in IEEE Std. 450-1995.
