PLANT SYSTEMS BASES 3/4.7.1.2 AUXILIARY TEEDVATER SYSTEMS (Continued)

Following any modifications or repairs to the Auxiliary Feedvater System piping from the Condensate Storage Tank through auxiliary feed pumps to the steam generators that could affect the system's capability to deliver vater to the steam generators, following extended cold shutdovn, a flow path verification test shall be performed, This test may be conducted in HODES 4, 5 or 6 using auxiliary steam to drive the aur.111ary feed pumps turbine to demonstrate that the flow path exists from the Condensate Storage Tank to the l steam generators via auxiliary feed pumps.

Verification of the turbine plant cooling water valves (CV 196 and CV 197),

the startup feedvater pump suction valves (FV 32 and FV 71), and the startup f eedvater pump discharge valve (FV 106) in the closed position is required to address the concerns associated with potential pipe f ailures in the auxiliary feedvater pump rooms, that could occur during operation of the startup feedvater pump.

T 4Jss 3/4.7.1.3 CONDENSATE STORAG Wreftf8Pitt j l j The OPERABILITY of the Condensate Storage Tahith the minimum vater volume l ensures that sufficient vater is available to maintain the RCS at HOT STANDBY conditions for 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> with steam discharge to atmosphere and to cooldovn the Reactor Coolant System to less than 280'T in the event of a total loss of offsite power or of the main feedvater system. The contained water volume <

limit includes an allowance for vater not usable because of tank discharge line location or other physical characteristics.

i 3/4.7.1.4 ACTIVITY The limitations on secondary system specific activity ensure that the resultant offsite radiation dose vill be limited to a small fraction of 10 CFR Part 100 limits in the event of a steam line ruptu19. This dose includes the effects of a coincident 1.0 GPM primary to accondary tube leak in the steam generator of the affected steam line. These values are consistent with the assumptions used in the safety analyses.

}/447.1.5 MAIN STEAM LINE ISOLATION VALVES The OPERABILJTY of the main steam line isolation valves ensures that no more than one steam generator vill blovdown in the event of a steam c line rupture. This restriction is required to 1) minimize the DAVIS-BESSE, UNIT 1 8 3/4 7-2 Amendment No. 58, 96, 122 )
