As nuclear power system modeling increasingly moves towards greater accuracy and refinement,research on the coupling of three-dimensional core and thermal-hydraulic models has also grown,which provides a better model foundation for the design of control systems.In this study,the APROS software was used to model the coupling of a three-dimensional core and thermal hydraulics for VVER-1000.A load-following control system based on model predictive control(MPC)and other control systems were designed.The model was then verified using steady-state and transient simulation results,which showed that the model simulated effectively.Taking advantage of the three-dimensional core visualization,the performance and safety of the MPC load-following controller were further validated.This research not only provides a model foundation for studies on nuclear power systems but also offers practical experience for the safety analysis of advanced power control systems.
