A.C. SOURCES. D.C. SOURCES. AND ONSITE POWER DISTRIBUTION (Continued)

The Surveillance Requirement for demonstrating the OPERABILITY of the station batteries is 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."

The modified performance discharge test is described in the April 24, 1992 Draft Revision to IEEE Std 450, "IEEE Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-Acid Batteries for Stationary Applications."

It is permissible to perform a modified performance discharge test on the AT&T battery in lieu of a service test and a performance discharge test as required by Regulatory Guide 1.129, Regulatory Position C.1, because the test discharge rate envelopes the load cycle of the service test.

Verification of the crosstie loading limits in Specifications 3.8.2.1 and 3.8.2.2 ensures that the OPERABLE battery will have sufficient capacity to energize the design basis loads of its DC bus while maintaining the limited DC loads of the inoperable DC bus on a shutdown unit.

Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, 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.

The battery service test is a special test of battery ca ability, as-found, to satisfy the design requirements (battery duty cycle of the D.C.

electrical power system. The discharge rate and length of th battery service test corresponds to the design duty cycle requirements as specified in UFSAR Subsection 8.3.2.1.1.

Table 4.8-2 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 desi nated pilot cells float voltage and specific gravity, greater than 2.18 volts AT&T manufacturer's full charge specif c gra)vity or a battery charger current that2.13 volts (

had stabilized at a low value is characteristic of a charged cell with d

adequate capacity. The normal limits for each connected cell for float voltage and specific gravity, greater than 2.18 volts and not l

more than 0.020 below the manufacturer's full c(AT&T) 2.13 volts (Gould)ith harge specific gravity w j

average specific the manufacturer' gravity of all the connected cells not more than 0.010 below s full charge specific gravity, ensures the OPERABILITY and capability of the battery.

Operation with a battery cell's parameter outside the normal limit but within the allowable value specified in Table 4.8-2 is permitted for up to 7 days.

During this 7-day period:

(1) the allowable values for electrolyte level ensures no physical damage to the plates with an adequate electron transfer capabilit of all the cells, y; (2) the allowable value for the average specific gravity not more than 0.020 below the manufacturer's recommended full charge specific gravity, ensures that the decrease in rating will be less than the safety margin provided in sizing; (3) individual cell's specific gravity the allowable value for an individual cell's specific gravity, ensures that an will not be more than 0.040 below the manufacturer's full charge specific gravity and that the overall capability of the battery will be maintained within an acceptable limit; and (4)2.14 volts (AT&T) 2.07 volts (Gould),

the allowable value for an individual cell's float voltage, greater than ensures the battery's capability to perform its design function.

The Surveillance Requirement for demonstrating the OPERABILITY of the station batteries is 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."

The modified performance discharge test is described in the April 24, 1992 Draft Revision to IEEE Std 450, "IEEE Recommended Practice for Maintenance, Applications." placement of Vented Lead-Acid Batteries for StationaryIt is permissible to p Testing and Re test on the AT&T battery in lieu of a service test and a performance discharge test as required by Regulatory Guide 1.129, Regulatory Position C.1, because the test discharge rate envelopes the load cycle of the service test.

Verification of the crosstie loading limits in Specifications 3.8.2.1 and 3.8.2.2 ensures that the OPERABLE battery will have sufficient capacity to energize the design basis loads of its DC bus while maintaining the limited DC loads of the inoperable DC bus on a shutdown unit.

Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, 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.

The battery service test is a special test of battery ca ability, as-found, to satisfy the design requirements (battery duty cycle of the D.C.

electrical power system.

The discharge rate and length of th battery service test corresponds to the design duty cycle requirements as specified in UFSAR Subsection 8.3.2.1.1.

Table 4.8-2 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 2.18 volts and 0.015 below the l

manufacturer's full charge specif(AT&T) 2.13 volts (Gould)harger current that ic gravity or a battery c had stabilized at a low value, is characteristic of a charged cell with adequate capacity.

The normal limits for each connected cell for float voltage and specific gravity, greater than 2.18 volts (AT&T and not more than 0.020 below the manufacturer's full charge) 2.13 volts (Gould)ith an specific gravity w average specific gravity of all the connected cells not more than 0.010 below the manufacturer's full charge specific gravity, ensures the OPERABILITY and capability of the battery.

Operation with a battery cell's parameter outside the normal limit but within the allowable value specified in Table 4.8-2 is permitted for up to 7 days. During this 7-day period:

(1) the allowable values for 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 0.020 below the manufacturer's recommended full l

charge specific gravity, ensures that the decrease in rating will be less than the safety margin provided in sizing; (3) the allowable value for an individual cell's specific gravity, ensures that an individual cell's specific gravity will not be more than 0.040 below the manufacturer's full charge specific gravity and that the overall capability of the battery will be maintained within an acceptable limit; and (4) the allowable value for an individual cell's float voltage, greater than 2.14 volts (AT&T) 2.07 volts (Gould),
