Transient stratification modelling of a corium pool in a LWR vessel lower head

•A kinetic stratification model is proposed for the simulation of the in-vessel corium behaviour during a LWR severe accident.•The different associated “modes” of vessel failure by thermal focusing effect are highlighted and discussed.•A sensitivity study for a 1650MWe GenIII PWR is presented with t...
