Abstract EN
The present paper systematically investigated pore scale thermal hydraulicscharacteristics of molten salt cooled high temperature pebble bed reactor.
By using computational fluid dynamics (CFD) methods and employing simplified body center cubic (BCC) and face center cubic (FCC) model, pressuredrop and local mean Nusselt number are calculated.
The simulation result shows that the high Prandtl number molten salt in packed bed has unique fluid-dynamics and thermodynamic properties.
There are divergences betweenCFD results and empirical correlations’ predictions of pressure drop and local Nusselt numbers.
Local pebble surface temperature distributions in several default conditions are investigated.
Thermal removal capacities of molten salt are confirmed in the case of nominal condition; the pebble surface temperature under the condition of local power distortion shows the tolerance of pebble in extreme neutron dose exposure.
The numerical experiments of local pebble insufficient cooling indicate that in the molten salt cooled pebble bed reactor, the pebble surface temperature is not very sensitive to loss of partial coolant.
The methods and results of this paper would be useful for optimum designs and safety analysis of molten salt cooled pebble bed reactors.
