Modelling of debris bed reflooding in PEARL experimental facility with MC3D code

•MC3D simulations of PEARL experiments are presented.•The general trends of the flows are recovered and explained.•The 2-D behaviour, with faster progression in the bypass, is highlighted and explained.•The impact of porosity in the 2-D reflooding configurations is presented. A hypothetical severe a...
