Abstract

The STYX test facility which is designed to investigate the coolability of heat-generating core debris beds has been applied to study the effect of lateral flooding on the dry-out heat fluxes of porous particle beds. The test rig was modified by installation of three downcomer tubes that feed cooling water to inlets near the bottom of the particle bed by natural circulation. It was observed that the dry-out heat flux in a homogenous test bed was increased approximately 20-25%. For a stratified bed with a layer of fine particles on top of the bed no significant increase was observed. The WABE/MEWA porous media code has been utilized in modeling of the coolability tests.
