Vapour explosions may occur when a hot liquid comes into contact with a cold volatile liquid.
They are caused by rapid and coherent transfer of heat energy between the two fluids …

Steam explosion phenomena in stratified melt-coolant configuration are considered in this
paper. Liquid corium layer covered by water on top can be formed in severe accident …

A hypothetical severe accident in a nuclear power plant can lead to significant core damage,
including melting of the core. The interaction between the molten core and the coolant water …

High-temperature melt spreading under a shallow water layer can lead to energetic
interaction, known as the stratified steam explosion. One of the key uncertainties in the …

Release of core melt from failed reactor vessel into a pool of water is adopted in several
existing designs of light water reactors (LWRs) as an element of severe accident mitigation …

We consider steam explosion in stratified melt–coolant configuration. Such configuration,
with a liquid corium layer covered by water on top, can be formed in severe accident …

In the recent fuel–coolant interaction experiments performed in the stratified configuration at
the SES and PULiMS facilities (KTH, Sweden), a premixed layer of ejected melt drops in …

Dynamics of a multiphase flow phenomenon involving water (at top), molten metal (at
bottom), and vapor (between them), was numerically studied using volume of fluid method …

The propagation of a vapor explosion in a stratified molten tin/water system has been
investigated experimentally in two different geometrical configurations:(i) linear propagation …

ABSTRACT""'••• A mechanistic model is developed to predict the transition superficial gas
velocity between bulk cooldown and crust-limited heat transfer regimes in a sparged molten …
