During a severe accident in nuclear reactors, the core may melt and relocate into the lower
head. The decay power in the accumulated melt pool will threaten the integrity of the reactor …

Due to the high-Rayleigh-number natural convection and strong turbulence in the
volumetrically heated corium melt pools, it is difficult to capture the heat transfer …

In the severe accident of nuclear reactors, the melt stratification and migration in debris bed
directly affect the melt heat transfer characteristics and the heat flux distribution on the lower …

This paper presents the results from COPRA eutectic molten salt tests, which were carried
out to investigate the simulant effect on corium pool natural convection heat transfer …

In a hypothetical severe accident scenario in light water reactors (LWR), after the loss of
primary coolant, the melted core moves to the lower plenum of the reactor pressure vessel …

In this study, the transient behavior of two-layer corium pool was studied based on COPRA
facility. The transient change of two-layer corium pool caused by power change and the …

In-vessel retention (IVR) is considered as an effective mitigation strategy in realms of nuclear
safety. Extensive experimental investigations have been done on the natural convection …

In this study, the effect of the stratified interface instability on the thermal focusing effect in
two-layer corium pool were investigated by numerical simulations performed with CFD code …

Coolability and retention of core melt (corium) in the lower head of reactor pressure vessel
(RPV) has been accepted as a severe accident management strategy to maintain the reactor …

This paper describes the main research lines of the Karlsruhe Institute of Technology (KIT)
relevant to Light Water Reactors (LWR) that permit both the safety evaluation of different …
