BASES APPLICABLE SAFETY ANALYSES LCO APPLICABILITY Rev 7 Diesel Fuel 011, Lube 011, and Starting Air 8383 The 1rnt1al cond1t1ons of Design Basis Accident (OBA) and transient analyses 1n FSAR, Chapter 6 (Ref 4), and Chapter 15 (Ref 5), assume Engineered Safety Feature (ESF) systems are OPERABLE The DGs are designed to provide sufficient capacity, capability, redundancy, and reliability to ensure the ava1lab1llty of necessary power to ESF systems so that fuel, Reactor Coolant System, and containment design limits are not exceeded These limits are discussed 1n more detail 1n the Bases for Section 3 2, Power D1stnbut1on L1m1ts, Section 3 4, Reactor Coolant System (RCS), and Section 3 6, Containment Systems Smee diesel fuel Oil, lube 011, and starting air subsystem support the operation of the standby AC power sources, they satisfy Cntenon 3 of the NRC Policy Statement (Ref 6)
Stored diesel fuel 01l 1s required to have sufficient supply for 7 days of full load operation It 1s also required to meet specific standards for quality Add1t1onally, sufficient lube Oil supply must be available to ensure the capability to operate at full load for 7 days This reqwrement, 1n conJunct1on with an ability to obtain replacement supplies within 7 days, supports the ava1lab1llty of DGs required to shut down the reactor and to maintain 1t 1n a safe cond1t1on for an ant1c1pated operational occurrence (AOO) or a postulated OBA with loss of offs1te power DG day tank fuel rnl requirements, as well as transfer capability from the storage tank to the day tank, are addressed in LCO 3 8 1, "AC Sources-Operating," and LCO 3 8 2, "AC Sources-Shutdown "
The starting air system 1s required to have a minimum capacity for five successive DG start attempts without recharging the air start receivers The AC sources (LCO 3 8 1 and LCO 3 8 2) are required to ensure the avallab1llty of the required power to shut down the reactor and maintain 1t 1n a safe shutdown cond1t1on after an AOO or a postulated OBA Because stored diesel fuel 011, lube rnl, and starting air subsystem support LCO 3 8 1 and LCO 3 8 2, stored diesel fuel 011, lube 011, and starting air are required to be within limits when the associated DG 1s required to be OPERABLE (continued)
SUSQUEHANNA-UNIT 2 3 8-48
BASES ACTIONS Rev 7 Diesel Fuel 011, Lube 011, and Starting Air 8383 The ACTIONS Table 1s modified by a Note md1cat1ng that separate Cond1t1on entry 1s allowed for each DG This 1s acceptable, since the Required Actions for each Cond1t1on provide appropnate compensatory actions for each inoperable DG subsystem Complying with the Required Actions for one inoperable DG subsystem may allow for continued operation, and subsequent inoperable DG subsystem(s) governed by separate Cond1t1on entry and application of associated Required Actions In this Cond1t1on, the 7 day fuel rnl supply for a DG 1s not available However, the Cond1t1on 1s restncted to fuel rnl level reductions that maintain at least a 6 day supply The fuel 011 level equivalent to a 6 day supply 1s 41,018 gallons for DG A-D and 52,340 gallons for DG E These circumstances may be caused by events such as a
Full load operation required for an inadvertent start while at minimum required level, or b
Feed and bleed operations that may be necessitated by 1ncreas1ng particulate levels or any number of other Oil quality degradations This restnct1on allows sufficient time for obtaining the requ1s1te replacement volume and performing the analyses required pnor to add1t1on of the fuel 011 to the tank A penod of 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> 1s considered sufficient to complete restoration of the required level prior to declaring the DG inoperable This period 1s acceptable based on the remaining capacity (> 6 days), the fact that action will be 1nit1ated to obtain replenishment, the ava1lab11ity of fuel 011 1n the storage tank of the fifth diesel generator that 1s not required to be OPERABLE, and the low probability of an event during this brief period With lube 011 sump level not v1s1ble m the sight glass, sufficient lube 011 to support 7 days of continuous DG operation at full load cond1t1ons may not be available Therefore, the DG 1s declared inoperable 1mmed1ately (continued)
SUSQUEHANNA - UNIT 2 3 8-49
BASES ACTIONS (continued)
Rev 7 Diesel Fuel 011, Lube 011, and Starting Air B383 This Cond1t1on 1s entered as a result of a failure to meet the acceptance cntenon for particulates Normally, trending of particulate levels allows suff1c1ent time to correct high particulate levels pnor to reaching the limit of acceptability Poor sample procedures (bottom sampling), contaminated sampling equipment, and errors 1n laboratory analysis can produce failures that do not follow a trend Since the presence of particulates does not mean failure of the fuel 011 to burn properly in the diesel engine, since particulate concentration 1s unlikely to change significantly between Surveillance Frequency intervals, and since proper engine performance has been recently demonstrated (w1th1n 31 days), 1t 1s prudent to allow a bnef period pnor to declaring the associated DG inoperable The 7 day Completion Time allows for further evaluation, resamphng, and re-analysis of the DG fuel 011 With the new fuel Oil properties defined 1n the Bases for SR 3 8 3 3 not w1th1n the required limits, a period of 30 days 1s allowed for restoring the stored fuel OJI properties This penod provides sufficient time to test the stored fuel OJI to determine that the new fuel OJI, when mixed with previously stored fuel OJI, remains acceptable, or to restore the stored fuel OJI properties This restoration may involve feed and bleed procedures, filtering, or combination of these procedures Even 1f a DG start and load was required dunng this time interval and the fuel OJI properties were outside limits, there 1s high likelihood that the DG would still be capable of performing its intended function With starting air receiver pressure < 240 ps1g 1n one or more air receivers, suff1c1ent capacity for five successive DG start attempts can not be provided by the air start system However, as long as all receiver pressures are > 180 ps1g, there rs adequate capacity for at least one start attempt, and the DG can be considered OPERABLE while the arr receiver pressure 1s restored to the required limit A penod of 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> 1s considered sufficient to complete restoration to the required pressure prior to declaring the DG inoperable This period 1s acceptable based on the remaining air start capacity, the fact that most DG starts are accomplished on the first attempt, and the low probability of an event dunng this bnef penod Entry into Cond1t1on E rs not required when air receiver pressure 1s less than required limits following a successful start while the DG 1s operating (continued)

Rev 7 Diesel Fuel 011, Lube 011, and Starting Air 8383 The pressure specified 1n this SR 1s intended to reflect the lowest value at which the five starts can be accomplished The air starting system capacity for each start cycle,s calculated based on the following 1
each cranking cycle duration should be approximately three seconds,or 2
consist of two to three engine revolutions, or 3
air start requirements per engine start provided by the engine manufacturer, whichever air start requirement 1s larger This Surveillance 1s modified by a Note, which does not require the SR to be met when the associated DG 1s running This 1s acceptable because once the DG 1s started the safety function of the air start system 1s performed The Surveillance Frequency 1s controlled under the Surveillance Frequency Control Program SR 3 8 3 5 M1crob1olog1cal fouling 1s a maJor cause of fuel Oil degradation There are numerous bacteria that can grow m fuel 011 and cause fouling, but all must have a water environment m order to survive Removal of water from the fuel storage tanks periodically eliminates the necessary environment for bacterial survival This,s the most effective means of controlling m1crob1olog1cal fouling In add1t1on, 1t eliminates the potential for water entrainment m the fuel 011 during DG operation Water may come from any of several sources, including condensation, ground water, ram water, contaminated fuel 011, and from breakdown of the fuel Oil by bacteria Frequent checking for and removal of accumulated water m1rnm1zes fouling and provides data regarding the watertight integrity of the fuel 011 system The Surveillance Frequency 1s controlled under the Surveillance Frequency Control Program (continued)
