Each electric dri ven auxiliary feedwater pump is capable of deliver-ing a total feedwater flow of 440 gpm at a pressure of 1150 psig to the entrance of the steam generators.
The steam driven auxiliary feedwater pump i s capable of deliveiing a total feedwater flow of 880 gpm at a press u: e of 1150 psig to the entrance of the steam generators.
This capacity i s sufficient to ensure that adequate feedwater flow is available to remove decay heat and reduce the Reactor Coolant System temperature to less than 350°F when the Residual Heat Removal System may be placed into operation.

A spool piece consisting of a length of pipe may be used as an equivalent to a locked open manual valve.
The manual valves in the flow path are: lAFl, 11AF3, 12AF3, 13AF3, llAFlO, 12AF10, 13AF10, 14AF10, 11AF20, 12AF20, 13AF20, 14AF20, 11AF22, 12AF22, 13AF22, 14AF22, 11AF86, 12AF86, 13AF86, and 14AF86.
-e PUNT SYSTEMS AUXILIARY FEEDWATER SYSTEM LIMITING CONDITION FOR OPERATION 3.7. 1.2 At least three independent steam generator auxiliary feedwater pumps and associated manual activation switches in the control room and flow paths shall be OPERABLE with:
- a.
Two feedwater pumps, each capable of being powered from separat.e vital busses, and
- b.
One feedwater pump capable of being powered from an OPERABLE steam supply system.
APPLICABILITY:
MODES 1, 2 and 3.
ACTION:
- a.
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 />.

- 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 REQUIREMENTS 4.7. 1.2 Each auxiliary feedwater pump shall be demonstrated OPERABLE:
- a.
At least once per 31 days by:
- 1.
Verifying that each motor-driven pump develops a discharge pressure of greater than or equal to 1275 psig on recirculation flow.
- 2.
Verifying that the steam turbine-driven pump develops a discharge pressure of greater than or equal to 1500 psig on recirculation flow when the secondary steam supply pressure is greater than 750 psig.
The provisions of Specification 4.0.4 are not applicable.
- 3.
Verifying that each non-automatic valve in the flow path that is not locked, sealed or otherwise secured in position, is in its correct position.
