MELCOR Capability Development for Simulation of Debris Bed Coolability

open access: yes, 2021
The severe accident management (SAM) strategy for a Nordic boiling water reactor (BWR) employs cavity flooding prior to vessel failure, so that the core melt (corium) discharged from the vessel could fragment and form a particulate debris bed. The key to
