SOURCES and ONSITE POWER DISTRIBUTION SYSTEMS (Continued)' q -The surveillance requirements for demonstrating the OPERABILITY of the-unit batteries are in accordance with the recommendations of Regulatory Guide 1.129 " Maintenance Testing and Replacement of Large Lead Storcge Batteries for Nuclear Power Plants," February 1978, and IEEE Std 450-1980, 't "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-i battery was sized,Ltotal battery terminal voltage onfloat charge, connection' ~ i 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 4.8.2.1-1 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 0.015 below the manufacturer's ful1~ 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 ficat voltage and specific gravity;- greater:than - 2.13 volts.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 ful.1-charge specific gravity,: ensures the i OPERABILITY and capability of the battery... Exceptions to the specific: gravity-t y requirements lare taken to allow for the normal-deviations: experienced after. t a battery discharge and subsequent recharge associated with ~a; service.or, per-formance discharge test. The specific gravity deviations are recognized by-l and discussed in IEEE 450-1980.- . Operation with a battery cell's parameter)outside the normal limit but' within the-allowable:value specified-in Table 4.8.2.1-1Lis permitted for up.- L to 7 days. During this 7 day period:--.(1) theLallowable values"for electrolyte j level ensures no physical damage to-the-plates with'an adequate' electron transfer h 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 3' specific gravity, ensures that.the decrease in rating will be less than the 4 safety margin provided in sizing; (3):the allowable value for an individual J L cell's specific gravity ensures that.an individual cell's specific gravity will L .not-be more than 0.040-below the manufacturer's full charge. specific gravity-J and that the overall capability of the battery will'be maintained within ani r acceptable limit; and-(4) the allowable value-for an individual cell's float-voltage, greater: than 2.07 volts, ensures the battery's capability to perform i its design function.
