At least once per 92 days on a STAGGERED TEST BASI! by:
l 1)
Verifying that on recirculation flow each motor-driven pump l
develops a differential pressure of greater than or equal to 1460 psid when tested pursuant to Specification 4.0.5; 2)
Verifying that on recirculation flow the steam turbine-driven l
pump develops a differential pressure of greater than or equal to 1640 psid when the secondary steam supply pressure is greater than 800 psig. The provisions of Specification 4.0.4 are not applicable for entry into MODE 3.
c.
At least once per 18 months during shutdown by verifying that each l
auxiliary feedwater pump starts as designed automatically upon receipt of an Auxiliary Feedwater Actuation test signal.
For the steam turbine-driven auxiliary feedwater pump, the provisions of Specification 4.0.4 are not applicable for entry into MODE 3.
4.7.1.2.2 An auxiliary feedwater flow path to each steam generator shall be demonstrated OPERABLE following each COLD SHUTDOWN of greater than 30 days prior to entering MODE 2 by verifying flow to each steam generator.
