AUXILIARY FEEDWATER SYSTEM LIMITING C0f:0ITION FOR OPERATION I
3.7.1.2 At least two independent steam generator auxiliary feedwater pumps and associated flow paths shall be OPERABLE with:
- a. One feedwater pump capable of being powered by an OPERABLE diesel with 3.450 gallons of fuel in its day tank, and
APPLICABILITY: MODES 1, 2 and 3.
ACTION:
With one auxiliary feedwater pump inoperable, restore the inoperable pump 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 4.7.1.2.1 Each auxiliary feedwater pump shall be demonstrated OPERABLE:
- a. At least once per 31 days by:
- 1. Verifying that the diesel-driven pump starts and develops a discharge pressure of >1580 psig at 1200 RPM engine speed on recirculation flow, and
- 2. Verifying that the steam turbine-driven pump starts and develops a discharge pressure of 3,1580 psig at 4560 RPM on recirculation flow when the secondary steam pressure is >800 psig. Indication of pump operability may be determined at lower pressures in Modes 2 or 3 by verifying that the steam turbine-driven pump starts and develops a discharge pressure of 1470 psig on recirculation ficw when the second-dry steam pressure is >275 psig, however, operation at full speed must be verified as soon as secondary steam pressure is increased above 800 psig.
