Abstract
Within SARNET, the corium topic covers all the behaviors
of corium from early phase of core degradation to in or
ex-vessel corium recovery with the exception of corium
interaction with water, direct containment heating and
fission product release. The corium topic regroups in
three work packages the critical mass of competence
required to improve significantly the corium behavior
knowledge. The spirit of the SARNET networking is to
share the knowledge, the facilities and the simulation
tools for severe accidents, so to reach a better
efficiency and to rationalize the R&D effort at European
level. Extensive benchmarking has been launched in most
of the areas of research. These benchmarks were mainly
dedicated to the recalculation of experiments, while, in
the next periods, a larger focus will be given to
integral experiments or reactor applications. Eventually,
all the knowledge will be accumulated in the ASTEC severe
accident simulation code through physical model
improvements and extension of validation database. This
paper summarizes the progress that has been achieved in
the frame of the networking activities. A special focus
is placed on the melt pool and debris coolability and
corium-concrete interaction, in which, the effects due to
multidimensional geometries and heterogeneities has been
shown, during SARNET, to play a crucial role and for
which further research is still needed.
