DESCRIPTION:As the pivotal equipment connecting the primary and secondary l
 oops of pressurized water reactor nuclear power plants\, the dynamic therm
 o-hydraulic characteristics of the nuclear steam generator are directly re
 lated to the safe and stable operation of the unit. However\, traditional 
 modeling approaches suffer from poor versatility and low efficiency\, maki
 ng it difficult to meet the R&D demands for diverse application scenarios 
 and iterative optimization. Addressing these bottlenecks\, this paper prop
 oses a modular modeling and dynamic simulation method for nuclear steam ge
 nerators based on the Modelica language. First\, based on a hierarchical m
 odeling approach\, component-level models covering plena\, pipes\, heat st
 ructures\, steam-water separators\, and feedwater plena are constructed to
  achieve free configuration and visual simulation modeling. Second\, accor
 ding to the operating principles and structure of the nuclear steam genera
 tor\, a complete dynamic simulation model is assembled using these compone
 nt-level models. Finally\, the established model is validated against the 
 RELAP5 code to verify the effectiveness and reliability of the proposed me
 thod. The results indicate that the Modelica-based steam generator simulat
 ion model combines high accuracy with high efficiency\, providing signific
 ant technical support for the rapid design and verification of nuclear pow
 er systems.
