Complete meltdown of an LWR core may lead to rapid penetration of the pressure vessel and thermal interaction between core materials and concrete in the reactor cavity in the absence of intervention by engineered reactor safety features. Subsequent core-concrete interactions impact upon containment integrity by containment pressurization, production of combustible gases, and basemat erosion. The CORCON code represents the state of the art calculational tool for calculating the consequences of the attack of molten core materials upon concrete. This paper addresses the phenomenon of heat transfer between immiscible overlying corium layers agitated by gas release from the concrete which is one of the dominant heat transfer processes that needs to be modelled for accurate calculations of core-concrete interactions by CORCON.
