which are designated as Train A, receive A-train air, and provide flow to the l

same steam generators that are supplied by the B-train motor-driven auxiliary feedwater pump.

The remaining two LCVs are designated as Train 8, receive B-train air, and provide flow to the same steam generators that are supplied by the A-train motor-driven pump. This design provides the required redundancy to ensure that at least two steam generators rer e the necessary flow assuming any single failure.

It can be seen from th cription provided above that the loss of a single train of air (A or B) not prevent the auxiliary feed-water system from performing its intended sa.ety function and is no more severe than the loss of a single auxiliary feedwater pump. Therefore, the loss of a single train of auxiliary air only affects the capability of a single motor-driven auxiliary feedwater pump because the turbine-driven pump is still casable of providing flow to two steam generators that are separate from the ot1er motor-driven pump.

Two redundant steam sources are required to be operable to ensure that at least one source is available for the steam-driven auxiliary feedwater (AFW) pump operation following a feedwater or main steam line break. This require-ment ensures that the plant remains within its design basis (i.e., AFW to two intact steam generators) given the event of a loss of the No. I steam generator because of a main steam line or feedwater line break and a single failure of the B-train motor driven AFW pump. The two redundant sources must be aligned such that No. I steam generator source is open and operable and the No. 4 steam generator source is closed and operable.

For instances where one train of emergency raw cooling water (ERCW) is declared inoperable in accordance with technical specifications, the AFW turbine-driven pump is considered operable since it is supplied by both trains of ERCW. Similarly, the AFW turbine-driven pump is considered operable when one train of the AFW loss of power start function is declared inoperable in accordance with technical specifications because both 6.9 kilovolt shutdown board logic trains supply this function.

This position is consistent with American National Standards Institute /ANS 58.9 requirements (i.e., postulation 4

of the failure of the opposite train is not required while relying on the TS limiting condition for operation).

3/4.7.1.3 CONDENSATE STORAGE TANK The OPERABILITY of the condensate storage tank with the minimum water i

volume ensures that sufficient water is available to maintain the RCS at HOT STANDBY conditions for 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months with steam discharge to the atmosphere concur-rent with total loss of off-site power. The contained water volume limit includes an allowance for water not useable because of tank discharge line location or other physical characteristics.

SEQUOYAH - UNIT 2 3/4 3-39 Amendment No. 39,174,180,197 l

f PLANT SYSTEMS BASES i

j train air, and provide flow to the same steam generators that are supplied by the A-train motor-driven pump. This design provides the required redundancy to i

ensure that at least two steam generators receive the necessary flow assuming any single failure.

It can be seen from the description provided above that the loss of a single train of air (A or B) will not prevent the auxiliary feed-i water system from performing its intended safety function and is no more severe j

than the loss of a single auxiliary feedwater pump. Therefore, the loss of a single train of auxiliary air only affects the capability of a single motor-4 driven auxiliary feedwater pump because the turbine-driven pump is still capable of providing flow to two steam generators that are separate from the other motor-driven pump.

Two redundant steam sources are required to be operable to ensure that at i

least one source is available for the steam-driven auxiliary feedwater (AFW) j pump operation following a feedwater or main steam line break. This require-ment ensures that the plant remains within its design basis (i.e., AFW to two intact steam generators) given the event of a loss of the No. I steam generator l

because of a main steam line or feedwater line break and a single failure of the B-train motor driven AFW pump.

The two redundant sources must be aligned such that No.1 steam generator source is open and operable and the No. 4 steam generator source is closed and operable.

l For instances where one train of emergency raw cooling water (ERCW) is declared inoperable in accordance with technical specifications, the AFW turbine-driven pump is considered operable since it is supplied by both trains of ERCW. Similarly, the AFW turbine-driven pump is considered operable when one train of the AFW loss of power start fonction is declared inoperable in accordance with technical specifications because both 6.9 kilovolt shutdown board logic trains supply this function. This position is consistent with American National Standards Institute /ANS 58.9 requirements (i.e., postulation of the failure of the opposite train is not required while relying on the TS limiting condition for operation).

3/4.7.1.3 CONDENSATE STORAGE TANK The OPERABILITY of the condensate storage tank with the minimum water volume ensures that sufficient water is available to maintain the RCS at HOT STANDBY conditions for 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months with steam discharge to the atmosphere concur-rent with total loss of off-site power. The contained water volume limit includes an allowance for water not useable because of tank discharge line location or other physical characteristics.
