AUXILIARY FEEDWATER SYSTEM LIMITING CONDITION FOR OPERATION 3.7.1.2 Two independent steam generator auxiliary feedwater pumps and associated flow paths shall be OPERABLE.

, APPLICABILITY: MODES 1, 2 and 3.

ACTION:

a. With one auxiliary feedwater system inoperable, restore the inoperable system 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 HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

f SURVEILLANCE REQUIREMENTS

4.7.1.2 Each auxiliary feedwater systgm shall be demonstrated OPERABLE:

w

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

1. Verifying that each steam turbine driven pump develops a i

differential pressure of > 1070 psid on recirculation _

flow when the secondary steam supply pressure is greater than 800 psia, as measured on PI SP 128 for pump 1-1 and PI SP 12A for pump 1-2.

2. Verifying that each valve (manual, power operated or automatic) in the flow path that is not locked, sealed or otherwise secured in position, is in its correct position.

b. At least once per 18 months, during :hutdown, by:

l' j 1. Verifying that each automatic valve in the flow path i

actuates to its correct position on an auxiliary feed-water actuation test signal.

2. Verifying that each pump starts automatica11y upon ADD cei fa
