The single largest post-accident load on e(ach diesel generator is the RHR pump.
-The Surveillance Requirement for removal of accumulated water from the fuel oil storage tanks is for preventive maintenance. The presence of water does not necessarily represent failure of the Surveillance Requirement, provided the accumulated water is removed during performance of the Surveillance.
Accumulated water in the fuel oil storage tanks constitutes a collection of water at a level that can be consistently and reliably measured. The minimum level at which accumulated water can be consistently and reliably measured in the fuel oil storage tank sump is 0.25 inches. Microbiological fouling is a major t:ause of fuel oil degradation. There are numerous bacteria that can grow in fuel oil and cause fouling, but all-must have a water environment in order to survive.
Removal of accmulated water from the fuel storage tanks once every (31) days eliminates the necessary environment for bacterial survival. This is the most effe:tive means of controlling microbiological fouling.
In addition, it eliminates the potential for water entrainment in the fuel oil during DG operation. Water may come from any of several sources, including condensation, ground water, rain tater, contaminated fuel oil, and from breakdown of the fuel oil by bacteria.
Frequent checking for and removal of accumulated water minimizes fouling and provides data regarding the watertight integrity of the fuel oil system. The Surveillance Frequencies are established by Regulatory Guide 1.137.
The surveillance requirements for demonstrating the OPERABILITY of the
-units batteries are in accordance with the recommendaticns of Regulatory Guide i.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," and-IEEE Standard 450-1995,
'IEEE Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-Acid Batteries for Stationary Ap>11 cations" except that certain tests will be' performed at least once every 24 montis.
Verifying average electrolyte-temperature above the minimum for which the battery was sized, total battery teminal 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.

The parameters in Table 4.B.2.1-1 are based on the manufacturer's recommendation.- These parameters assure the OPFRABILITY and capability of the battery to perform its design function.
The Category A and B limits are s>ecified for each designated pilot cell and cach connected cell for electrolyte leve1, float voltage and specific gravity.. Parameters e:ithin the Category A and B limits are characteristic of a fully charged cell. The limits for the float voltage-and specific gravity for each connected cell and the average-specific gravity of all of the connected cells ensures the OPERABILITY and capability of the battery.
The Category B allowable value for electrolyte level provides assurance that the plates are covered and adequate electron transfer will occur between the plates. The allowable value for cell voltage provides assurance tha+. the cell is not discharged and the battery is capable of performing its design functiots. The allowable value for specific gravity for an individual cell provides assurance that the overall capability of the battery will be maintained within acceptable limits. The allowable value for the average specific gravity of all the cells ensures that the decrease in rating will be less than the safety margin provided in the battery sizing.
With parameters of one or more cells, in ct.e or more batteries, not within limits (i.e., Category A limits not met or Category B limits not met, or Category A and B liaits not met) but within the Category B allowable value tpecified in Table 4.8.2.1-1, operation is permitted for seven (7) days. Verification that the Category B allowable values are met, provides assurance that during the time needed to restore the parameters to the Category A and B limits, the battery is still capable of performing its' intended function.
For indication outside Category A, a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is allowed to complete the requirement because specific gravity measurements must be.taken for each connected cell. The specific gravity Category A limit and the Category B allowable value for each connected cell and the-average of all connected cells is modified by Note 6.
This note allows the use of charging current to verify the battery's state of charge. Charging current stability at a low rate is an indication that the
-battery is fully charged. This method provides a reliable measure of the battery's state of charge.
Continued operation is only permitted for severs (7) days before the battery cell parameters must be restored to within Category A and B limits. Taking into consideration that, while battery capacity may be degraded, sufficient capacity exists, based on meeting the Category B allowable values, to perform the intended function and to allow time to restorc the battery cell to its ncrmal limits. When any battery parameter for each connected cell is outside the Categcry B allowable value, sufficient capacity to supply the maximum load requirement is not assured and the corresponding de electrical power subsystem (i.e., battery) must be declared inoperable.
