【 摘 要 】

In order to study the thermal-hydraulics characteristics of a floating nuclear power plant (FNPP) system, a series of modeling studies are made for the safety analysis. By establishing a centrifugal pump model, the paper emphatically calculated a series of pump operating behaviors, such as steady-state operation, switching speed condition, starting condition and coastdown condition. The results show that the model can realize the corresponding simulation function and reflect the operation characteristics of the FNPP pump accurately. In addition, the selection of energy ratio for FNPP pump is highly demanding. The simulation model is suitable for the subsequent analysis of different FNPP reactor responses.s.
