SOURCES AND ONSITE POWER DISTRIBUTION SYSTEMS (Continued) 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 capacity at that time with the rated capacity.

Table 3.8-1 specifies the normal limits for each designated pilot call 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 that had stabilized at a low value, is characteristic of a charged cell with adequate capacit.y.

The normal limits for each connected cell for float voltap 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 capability of the battery.

i Operation with a battery cell's parameter outside the normal limit but within the allowable value specified in Table 3.8-1 is permitted for l

up to 7 days.

During this 7 day period:

(1) the allowable values for j

electrolyte level ensures no physical damage to the plates with an adequate electron transfer capability; (2) the allowable value for the average specific gravity of all the cells, not more than.020 below i

the manufacturer's recommended full charge specific gravity, ensures i

that the decrease in rating will be less than the safety margin i

provided in sizing; (3) the allowable value for an individual cell's i

specific gravity, ensures that an individual cell's specific gravity will not be more than.040 below the manufacturer's full charge specific gravity and that the overall capability of the battery will I

be maintained within an acceptable limit; and (4) the allowable value for an individual cell's float voltage, greater than 2.07 volts, l

ensures the battery's capability to perform its design function.

Note (1) provides clarification of Specification 3.8.1.1 action l l

Footnote (6) permits an engineering evaluation to be performed if the frequency limits of SR 4.8.1.1.2.b.3.b are not met.

The frequency limits prescribed in SR 4.8.1.1.2.b.3.b are based on full load conditions.

Since SR 4.8.1.1.2.b.3.b is normally performed at less than full loading conditions, the resultant generator frequency may exceed the required frequency value range due to the design of the diesel generator governor, especially during lower loading.

Under i

these conditions, it is acceptable to examine the frequency respons4 vs. loading and by an engineering evaluation, determine that tha governor is responding properly and would fall within the required frequency band while at full accident loading.

The engineering evaluation consists of comparing previous voltage, frequency and power plots with the current plots of these same parameters.

By' comparing the above data, proper governor response can be verified.

Based on governor response and the current governor droop setting, the frequency value obtained during performance of SR 4.8.1.1.2.b.3.b can be evaluated to ensure the frequency limits of SR 4.8.1.1.2.b.3.b at full accident loading would be met.
