A 3D heat conduction model for block-type High Temperature Reactors and its implementation into the Code DYN3D
Baier, S.; Kliem, S.; Rohde, S.
The code DYN3D, devoloped at the Helmholtzzentrum Dresden-Rossendorf, is extended for application of block-type High Temperature Reactors.
It involves a 3D heat conduction model to deal with higher-(than one)-dimensional effects of heat transfer and heat conduction in a block-type HTR. The heat conduction model is coupled with the existing thermal-hydraulic channel model of DYN3D. Fully-coupled (hexagonal) neutron kinetics and thermal hydraulics calculations are performed. It is shown that the model is appropriate to simulate both stationary states and short-time transients (sudden change of reactivity, sudden increase of the inlet coolant temperature) in a block-type HTR.
Keywords: high temperature gas cooled reactor; heat conduction model; transient analysis; computer code; temperature reactivity feedback
