A method (200; 300) for providing override control for a feedwater pump recirculation valve, the method (200; 300) comprising: receiving one or more measurements associated with pump motor power, wherein the feedwater pump recirculation valve is configured to maintain a predetermined minimum recirculation flow through the feedwater pump by regulating recirculation pump flow through a recirculation line; based at least in part on the one or more measurements, calculating (210; 310) the recirculation pump flow; comparing (215; 315) the calculated recirculation pump flow to the predetermined minimum recirculation flow; and based at least in part on the comparing (215; 315), selectively providing (220; 350) an override control signal to the feedwater pump recirculation valve to selectively modify the recirculation pump flow, wherein the override control signal is to override a signal provided by a differential-pressure flowmeter associated with the feedwater pump recirculation valve, the step comprising: determining (335-YES; 320-YES) that the signal provided by the differential-pressure flowmeter indicates that the recirculation pump flow is above the predetermined minimum recirculation flow (335-YES) whereas the calculated recirculation pump flow based on the one or more measurements is below the predetermined minimum recirculation flow (320-YES); and based at least in part on the determining (335-YES, 320-YES), providing the override control signal to the feedwater pump recirculation valve to increase the recirculation pump flow above the predetermined minimum recirculation flow. receiving one or more measurements associated with pump motor power, wherein the feedwater pump recirculation valve is configured to maintain a predetermined minimum recirculation flow through the feedwater pump by regulating recirculation pump flow through a recirculation line; based at least in part on the one or more measurements, calculating (210; 310) the recirculation pump flow; comparing (215; 315) the calculated recirculation pump flow to the predetermined minimum recirculation flow; and based at least in part on the comparing (215; 315), selectively providing (220; 350) an override control signal to the feedwater pump recirculation valve to selectively modify the recirculation pump flow, wherein the override control signal is to override a signal provided by a differential-pressure flowmeter associated with the feedwater pump recirculation valve, the step comprising: determining (335-YES; 320-YES) that the signal provided by the differential-pressure flowmeter indicates that the recirculation pump flow is above the predetermined minimum recirculation flow (335-YES) whereas the calculated recirculation pump flow based on the one or more measurements is below the predetermined minimum recirculation flow (320-YES); and based at least in part on the determining (335-YES, 320-YES), providing the override control signal to the feedwater pump recirculation valve to increase the recirculation pump flow above the predetermined minimum recirculation flow. determining (335-YES; 320-YES) that the signal provided by the differential-pressure flowmeter indicates that the recirculation pump flow is above the predetermined minimum recirculation flow (335-YES) whereas the calculated recirculation pump flow based on the one or more measurements is below the predetermined minimum recirculation flow (320-YES); and based at least in part on the determining (335-YES, 320-YES), providing the override control signal to the feedwater pump recirculation valve to increase the recirculation pump flow above the predetermined minimum recirculation flow.
