DESCRIPTION:Nuclear power systems are complex multi-disciplinary systems in
 volving thermal hydraulics\, fluid mechanics\, control engineering and ele
 ctrical engineering. Comprehensive performance analysis and optimization o
 f such systems require coupled multi-disciplinary modeling and simulation.
  Nevertheless\, co-simulation via interfaces between separate single-disci
 pline simulation software brings numerous inherent drawbacks. Hualong One 
 is China’s domestically developed third-generation pressurized water rea
 ctor. To accelerate system modeling and simulation efficiency\, this paper
  independently develops the unified multi-disciplinary modeling library CG
 N_HPR V1.0 based on Modelica and the hierarchical modeling method\, with t
 he domestic MWorks simulation platform as the core development environment
 . Adopting a four-tier architecture consisting of basic\, component\, equi
 pment and system levels\, the library supports modular\, parameterized and
  visual modeling for streamlined simulation analysis\, and addresses the t
 echnical bottleneck of insufficient deep coupling in traditional multi-dis
 ciplinary simulation workflows. Typical operating conditions of Hualong On
 e are modeled and simulated using the proposed library\, which preliminari
 ly verifies the validity of the Modelica-based system simulation model. Th
 e results demonstrate that the Modelica-enabled simulation framework enabl
 es seamless integration of cross-disciplinary subsystems\, mitigates the d
 ifficulties in multi-disciplinary coupled simulation for nuclear power pla
 nts\, and improves overall system analysis and design capacity\, providing
  key technical support for unit safety assessment and operational optimiza
 tion.
