Steam explosion experiments revealed that there is a significant influence of the melt material properties on the fuel coolant interaction process. A reason for this observed significantly different behaviour for different melts could be the probably different melt droplets freezing due to different melt material properties. A melt droplets solidification model, by which the growth of the solid crust on the droplets surface during the premixing phase may be simulated, was developed with corresponding melt droplets fragmentation criteria.

An improved solidification influence modelling approach for Eulerian fuel-coolant interaction (FCI) codes was developed together with corresponding melt drop break up criteria. The developed models were implemented into the advanced FCI code MC3D in an appropriate conservation form.
