'LANT SYSTEMS AUXILIARY FEEDWATER SYSTEM LIMITING CONDITION FOR OPERATION 3.7. 1.2 At least three independent steam generator auxiliary feedwater pumps and associated flow paths shall be OPERABLE with:

a. Two motor-driven auxiliary feedwater pumps, each capable of being powered from separate emergency buses, and

b. One steam turbine-driven auxiliary feedwater pump capable. of being powered from an OPERABLE steam supply system.

APPLICABILITY: .MODES 1, 2, and 3.

ACTION:

With one auxiliary feedwater pump inoperable, restore the required auxiliary feedwater pumps to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

b. With two auxiliary feedwater pumps inoperable, be in at least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in HOT SHUTDOWN within the following 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> s.

C. With three auxiliary feedwater pumps inoperable, immediately initiate corrective action to restore at least one auxiliary feedwater pump to OPERABLE status as soon as possible.

SURVEILLANCE REOUIREMENTS 4.7.1.2.1 Each auxiliary feedwater pump shall be demonstrated OPERABLE-'.

At least once per 31 days on a STAGGERED TEST BASIS by:

1. Verif in that each motor driven um develo s a dischar e res-of reater tha or si at a recirculation flow of greater than or equal to 50 gpm.

2. Verifying that the steam turbine-driven pump develops a discharge pressure of greater than or equal to 1510 psig on a recircula-tion flow of'reater than or equal to 90 gpm when the second-ary steam supply pressure is greater than 210 psig. The pro-visions of Specification 4.0.4 are not applicable for entry into MODE 3; t.,i pass~<<'+at lr'dren temperatrroe Compensated *70'F)'s
