Modeling and Simulation Method Research for Swimming Pool Reactor Heating System

Taking the swimming pool reactor heating system with low temperature and atmospheric pressure as the research object, after system division and reasonable simplification and assumption of actual physical equipment, a dynamic mathematical model covering its basic function was established. This model includes point reactor neutron dynamics model, thermal-hydraulics model and thermal equipment model outside the reactor. The model was verified based on the simulation platform vPower. The results show that the model can correctly reflect the dynamic characteristics of swimming pool reactor heating system. Therefore, this model can be used to study operating conditions and verify the rationality of design data.
