Molten Core concrete Interaction (MCCI) is a complex process characterized by concrete ablation and volatile generation;Thermal and solutal convection in a bubble-agitated melt; Physico-chemical evolution of the corium pool with a wide solidification range (of the order of 1000 K).
Twelve experiments have been carried out in the VULCANO facility with prototypic corium and sustained heating.
The dry oxidic corium tests have contributed to show that silica-rich concrete experience an anisotropic ablation. This unexpected ablation pattern is quite reproducible and can be recalculated, provided an empirical anisotropy factor is assumed.
Dry tests with oxide and metal liquid phases have also yielded unexpected results: a larger than expected steel oxidation and unexpected topology of the metallic phase (at the bottom of the cavity and also on the vertical concrete walls). Finally,VULCANO has proved its interest for the study of mitigation solutions such as the COMET bottom flooding core catcher.
