A severe accident (SA) is defined as an incident involving melting of the nuclear reactor core
and the release of fission products (FP) from the fuel and their associated risks. In the SA …

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 …

This paper is concerned with debris bed coolability in a postulated severe accident of light
water reactors, where the debris particles are irregular and multi-sized. To obtain and verify …

In a hypothetical light water reactor (LWR) core-melt accident with corium release from the
reactor vessel, the ultimate containment integrity is contingent on coolability of the decay …

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 …

Ex-vessel termination of accident progression in Swedish type Boiling Water Reactors
(BWRs) is contingent upon efficacy of melt fragmentation, quenching, solidification and …

Sever accident mitigation strategy adopted in Nordic Boiling Water Reactors (BWRs)
employs a deep water pool below the reactor vessel to fragment and quench core melt and …

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 …

Coolability of heat-releasing debris bed is an important issue in the severe accident analysis
and management. Traditionally, theoretical studies of top or bottom-fed debris bed …

Corium melt fragmentation and cooling in a deep pool of water under reactor pressure
vessel are employed as severe accident mitigation strategy in a Nordic-type BWR. Core …
