Abstract EN
High thermal neutron fluxes are needed in some research reactors and for irradiation tests of materials.
A High Flux Research Reactor (HFRR) with an inverse flux trap-converter target structure is being developed by the Reactor Engineering Analysis Lab (REAL) at Tsinghua University.
This paper studies the safety of the HFRR core by full core flow and temperature calculations using the porous media approach.
The thermal nonequilibrium model is used in the porous media energy equation to calculate coolant and fuel assembly temperatures separately.
The calculation results show that the coolant temperature keeps increasing along the flow direction, while the fuel temperature increases first and decreases afterwards.
As long as the inlet coolant mass flow rate is greater than 450 kg/s, the peak cladding temperatures in the fuel assemblies are lower than the local saturation temperatures and no boiling exists.
The flow distribution in the core is homogeneous with a small flow rate variation less than 5% for different assemblies.
A large recirculation zone is observed in the outlet region.
Moreover, the porous media model is compared with the exact model and found to be much more efficient than a detailed simulation of all the core components.
