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 …

Fuel–coolant interaction is a complex mixing process that can occur during the course of a
severe accident in a nuclear power plant involving core melting and relocation. Under …

In the course of a severe accident in a nuclear power plant cooled or moderated by water,
the core might melt and flow down into the water. Under certain circumstances, a steam …

The main results of the major international activities related to fuel–coolant interactions (FCI)
of the last 4-year period are presented and a summary of the knowledge gained regarding …

Vapor explosions have been investigated both theoretically and experimentally for several
decades, focusing either on the vapor film, or on mechanical aspects. Where the main …

Steam explosion experiments revealed important differences in the efficiency between
simulant alumina and oxidic corium melts. The experimentally observed differences are …

The past two decades were mainly devoted to model validation and computer code
verification against global corium experiments, code application to reactor situations, and …

Steam Explosion is a destructive event that may arise from the mixing of the molten fuel
(corium) with the liquid coolant (water, sodium) during the course of a severe accident. Due …

This paper discusses the results of steam explosion experiments using molten material
consisting of UO2 and ZrO2 mixture, which is called corium, to simulate a prototypic steam …

TEXAS-VI is a transient, three-field, one-dimensional mechanistic model for the steam
explosion phenomena. A fuel solidification model and associated fragmentation criteria of …
