Abstract
Benchmarking work was recently performed for the issue of molten corium
concrete interaction (MCCI). A synthesis is given here. It concerns
first the 2D CCI-2 test with a homogeneous pool and a limestone
concrete, which was used for a blind benchmark. Secondly, the COMET-L2
and COMET-L3 2D experiments in a stratified configuration were used as a
post-test (L2) and a blind-test (L3) benchmark. More details are given
here for the recent benchmark considering a matrix of four reactor
cases, with both a homogeneous and a stratified configuration, and with
both a limestone and a siliceous concrete. A short overview is given on
the different models used in the codes, and the consistency between the
benchmark actions on experiments and reactor situations is discussed.
Finally, the major uncertainties concerning MCCI are also pointed out.
