AUXILIARY FEEDWATER SYSTEM T0 0 ""

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 />.

SURVEILLANCE REQUIREMENTS 4.7.1.2 Each Auxiliary Feedwater System shall be demonstrated OPERABLE:

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

1. Verifying that each steam turbine driven pump develops a differential pressure of > 1070 psid on recirculation flow when the secondary steam supply pressure is greater than 800 psia, as measured on PI SP 12B for pump 1-1 and PI SP 12A for pump 1-2.

2. Verifying that each valve (power operated or automatic) in the flow path is in its correct position.

. 3. Verifying that all manual valves in the auxiliary feedwater pump suction and discharge lines that affect the system's capacity to deliver water to the steam generator are locked in their proper position.

b. At least once per 18 months by:

1. Verifying that each automatic valve in the flow path actuates to its correct position on an auxiliary feedwater actuation test signal prior to entering MODE 3.

• 2. Verifying that each pump starts automatically upon receipt of an auxiliary feedwater actuation test signal prior to entering MODE 2.

3. Verifying that there is a flow path between each auxiliary feedwater pump and each steam generator by pumping water from the Condensate Storage Tank to the steam generator.

• Provision of section 3.0.4 is not applicable for entry into MODE 3.

.- THIS PAllE PROVIDED PLANT SYSTEMS FORINFORETION DE SURVEILLANCE REQUIREMENTS (Continued)

f. Following each extended cold shutdown (> 30 days in MODE 5), by:

1. Verifying that there is a flow path between each auxiliary feedwater pump and each steam generator by pumping Conden-sate Storage Tank water to the steam generator. The flow path to the steam generator shall be verified by either steam generator level change or Auxiliary Feedwater Safety Grade Flow Indication.

Verification of the Auxiliary Feedwater System's flow capacity is not_ required.
