SOURCES AND ONSITE POMER DISTRIBUTION SYSTEMS (Continued}

The surveillance requirement for demonstrating the OPERABILITY of the Station batteries are based, on'he re'commendations of Regulatory, Guide 1. 129, "Maintenance Testing and Replacement of Large Lead 'Storage Batteries for'uclear Power Plants,"

February 19?8, 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 float charge, connecti,on 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 She rated capacity.

Table 4.8-2 specifies the normal limits for each designated pilot cell and each connected cell for electrolyte level, float volta'ge and specific gravity.

The limits for the designated pilot cells 'float voltage and specific gravity, greater than 2, 13 volts (Exide) 2. 18 volts (ATILT) and 0. 010 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 capacity.

'The normal limits for each connected cell for float voltage and specific gravity, greater than 2. 13 volts (Exide) 2. 18 volts (ATILT) and not more than 0.020 below the manufacturer's full charge specific gravity with an 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'per iod:

(1}, the allowable'alues -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 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. 07 volts (Exide) 2.14 volts (ATILT),

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

If any other metallic structures (e. g., buildings, new or mo'dified piping

systems, conduit) are placed in the ground in the vicinity of the fuel oil stor-age system or if the original system is modified, the adequacy and frequency of inspections of the cathodic protection system shall be re"evaluated and ad" justed in accordance with Regulatory Guide l. 137.

ELECTRICAL POWER SYSTEHS BASES A.C.

SOURCES D.C. 'SOURCES AND ONSITE POWER DISTRIBUTION SYSTEHS (Continued)

The surveillance requirement for demonstrating the OPERABILITY of the Station batteries are based on the recommendations of Regulatory Guide l. 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 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 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. 13 volts (Exide) 2. 18 volts (ATILT) and 0.010 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 capacity.

The normal limits for each connected cell for float voltage and specific gravity, greater than 2. 13 volts (Exide) 2. 18 volts (ATILT) and not more than 0.020 below the manufacturer's full charge specific gravity with an 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 charge specific gravity, ensures that the decrease in rating wi 11 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 2.07 volts (Exide) 2.14 volts (ATILT),

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

If any other metallic structures (e.g., buildings, new or modified piping

systems, conduit) are placed in the ground in the vicinity of the fuel oil stor" age system or if the original system is modified, the adequacy and frequency of inspections of the cathodic protection system shall be re-evaluated and ad-justed in accordance with Regulatory Guide 1.137.
