Modeling of Heat-and-Mass Transfer in Fuel Assemblies in Liquid-Metal-Cooled Reactors with Partial Flow-Passage Blockage

Abstract

The results of modeling the heat-and-mass transfer in the FA of liquid metal cooled reactors with partial flow-passage blockage are presented. The model employed for an isotropic porous body is described, and the obtained results are compared with experimental data and with direct numerical modeling performed with the CONV-3D code. It is shown that the porous-body model developed can be used to analyze threedimensional heat-and-mass transfer processes arising when the flow passage area of FA is partially blocked.
