Advanced thermal hydraulics for training simulator enhancement
The thermal-hydraulic models in a nuclear power plant operator training simulator model the dynamics of the reactor coolant system and the steam generators in a pressurized water reactor or the nuclear boiler and recirculation system in a boiling water reactor (BWR). Although the operator trainee has limited direct interaction with these systems, they are the focal point of the simulation, because they are vital links in the power production process and because the auxiliary systems are coupled through them. The model described here retains the benefits of a physically based simulation, while delivering real-time performance. The model uses a true momentum balance, allowing it to simulate any flow condition. A transient momentum equation is created for each flow path by adding the contributions of each flow path node. This equation is integrated implicitly in flow, giving an equation for the flow in terms of the new pressure drop. A volume balance is applied to each system component, at which the flow paths meet, leading to a matrix equation for the new component pressures.
