Auxiliary Feedwater System Operation.
NOTE The recommended Steam Generator NR level band is 24% to 54%. (P&L 3.2)
CAUTION The following steps supply Steam Generators with full Aux Feedwater flow.
Any Steam Generator Level exceeding 67% will cause an ESF Actuation for Turbine Trip and Feedwater Isolation.
23 Auxiliary Feedwater Pump should be stopped if any SG NR Level is >55%470067944) 5.1.8 PERFORM the following to exercise Check Valve 21 AF921 to the full-stroke OPEN position:

Salern2 Page 6 of 24 Rev. 20
S2 .OP-ST.AF-0007(Q)
NOTE The recommended Steam Generator NR level band is 24% to 54%. (P&L 3.2)
CAUTION 4000 RPM should not be exceeded as turbine damage may result.
The following steps supply Steam Generators with full Aux Feedwater flow.
Any Steam Generator Level exceeding 67% will cause an ESF Actuation for Turbine Trip and Feedwater Isolation.
23 Auxiliary Feedwater Pump should be stopped if any SG NR Level is >55%. (70067944)
Additional steam flow during 23 Auxiliary Feedwater Pump operation and feeding Steam Generators at >44E04 Ibm/hr will cooldown the RCS. Pzr LvI should be maintained between 30-53% to prevent Letdown Isolation during testing.
Values outside of those listed in the acceptable range of S2.RA-ST.AF-0007(Q),
for Pump Total Flow Rate, do not necessarily make the pump inoperable, but do invalidate the performance of the procedure.
