The 31 day Frequency takes into account the capacity, capability, redundancy, and diversity of the AC sources and other indications.available in the control room, including alarms, to alert the operator to below normal air start pressure.

SR 3.8.3.5 g Microbiological fouling is a maj lr ause of fuel oil degradation. There are numerous b cteria that can grow in fuel oil and cause fouling, but l' must have a water environment in order to surviv . Memoval of water from the fuel storage tanks once every ly days eliminates the necessary environment for bac rial survival. This is the most effective means of controlling microbiological fouling.

In addition, it eliminates the potential for water entraicwnt in the fuel oil during DG operation. Water may come it as any of several sources, including condensation, ground water, rain water, and 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 (Ref. 2). This SR is g

T for preventive maintenance. The presence of water does not necessarily represent failure of this SR, provided the accumulated water is removed during performance of the Surveillance.

' ^^po allow alignment of the AFW pumps mini-flow lines to the CST to which the pump suction is aligned. Prior to the implementation of the design modification, LCO 3.7.6a shall be applicable. Prior to completion of the design modification the volume of water required to satisfy the safety analyses for a unit is 420,000 gallons. LCO 3.7.6a requires an unmodified unit to maintain both CSTs OPERABLE with a combined safety-related volume of 2420,000 gallons. In addition, LCO 3.7.6a requires the CST that supplies the AFW pumps to contain a safety-related volume of  ;

2340,000 gallons. The volume specified for the CST supplying the AFW System is based on i the need to ensure sufficient time exists for the operator action required to switch the AFW pump suction supply to the other CST. If the combined safety-related volume or the safety-related volume required for the AFW supply is not as specified, LCO 3.7.6a contains Actions to restore the volume (s) to within limit or to place the unit in a MODE where the CSTs are no l longer required OPERABLE. LCO 3.7.6a is no longer required and may be deleted when both units have completed the required modifications. l
