Research on Model Simulation Engine in Nuclear Reactor Control Software Development Environment

Research on a model simulation engine for the model-based development environment of nuclear reactor control software has been conducted. A model-execution-based simulation engine is proposed, and the overall architecture of the simulation engine along with key components such as the model loader, runtime executor, and structure collector are designed. The simulation engine was utilized to conduct single-step and continuous simulation experiments on the PID model of a reactor coolant flow control system. The simulation engine employs a trustworthy code generator to construct simulation executable models, ensuring complete consistency between simulation results and the intended behavior of the designed model (Simulink simulation results). During the simulation process, the simulation engine is capable of directly reading the model, accurately executing simulation calculations, visualizing simulation results, and achieving model simulation and analysis with precision and efficiency.
