主　　题：Heat transfer PRHR HX Transient analysis Optimization investigation 

摘      要：The transient performance and optimization of a passive residual heat removal heat exchanger(PRHR HX)were ***,a calculation method was developed for predicting the heat transfer of the PRHR *** calculation results were validated through comparisons with ROSA experimental *** heat-transfer performance of the AP1000 PRHR HX in the initial period was predicted,and it satisfied the design ***,the distributions of the heat flux,tube-inside/outside heattransfer coefficients,and heat load for the AP1000 PRHR HX over 2000 s were ***,an optimization study was conducted by adjusting the horizontal length and tube *** effects on the four main heat-transfer parameters and the heat-transfer area were ***,the influence of the initial in-containment refueling water storage tank(IRWST)temperature was investigated using an established simulation *** results indicated that it significantly affected the trends of the IRWST temperature and reactor outlet ***,the minimum required flow rates over time to maintain the reactor outlet temperature at the safety line were determined for different start-up *** trends of the minimum required flow rate and the peak flow rate were analyzed.
