[1C05] Verification of Neutronics-Thermalhydraulics Coupling UDF for FLUENT Code using MSRE Experiment
Analysisi of Pump Startup and Trip Experiment
Keywords:Molten Salt Reactor, MSRE, Pump startup and coastdown, Neutronics-thermalhydraulics coupling, FLUENT, PID control
Using the fuel pump startup and trip experiments of the thermal neutron molten salt reactor experiment, MSRE, which was in operation for four years since 1965 at Oak Ridge National Laboratory, the computation function of the User Defined Function (UDF) incorporated in the FLUENT code has been verified. A PID controller model of the control rod has been added to the UDF which had a function to calculate neutronics and thermal-hydraulics coupling.
