THE DYNAMICS OF A TURBINE-DRIVEN REACTOR FEEDWATER PUMP AND IDENTIFICATION OF RELATED PARAMETERS IN THE KUOSHENG-POWER-STATION

In the Kuosheng nuclear power station, a turbine-driven reactor feedwa ter pump (TDRFP) is used to drive feedwater to the reactor pressure ve ssel (RPV). The performance of the TDRFP plays an important role in th e safe operation of the nuclear power station as it governs the water inventory in the RPV. The dynamics of the TDRFP in the Kuosheng nuclea r power station are simulated, and related parameters are identified b y the simplex search method. A reactor feedwater pump (RFP) trip test was performed during the startup test of the Kuosheng nuclear power st ation. This RFP trip transient was selected for this study because it simplifies the identification process. The ratio of rated torque to mo ments of inertia, parameters related to the characteristic H-Q curve, and parameters related to the characteristic T-Q curve are verified.
