In the case of a severe accident with vessel melt-through, the Molten Core Concrete Interaction (MCCI) may take place and become a threat to the integrity of the containment, which is the ultimate barrier between the corium and the environment. During SARNET project (EURATOM 6th Framework programme) 41/2 years, experimental programs related to MCCI issues have been pursued on the VULCANO, HECLA, COMETA and ARTEMIS facilities and several benchmark exercises have been conducted, in particular on reactor scale applications. This issue has been considered within the SARNET project (2004-2008) to have a high priority. Within the new project SARNET2 (2009-2013), a significant experimental program on MCCI, coupled with joint interpretation, modelling and code applications, has been proposed in view of understanding these phenomena and towards closing the safety issue. This research program has been designed to ensure complementarity with the ongoing MCCI-2 project of the OECD-NEA. It will address the following issues: effect of the concrete nature on 2D ablation profiles, role of the metallic layer on the MCCI, and efficiency of water cooling to terminate the ablation of concrete. It will also have a specific focus on the transposition of R&D results to the reactor scale. More than 17 European organizations will contribute to these activities, which will include a significant experimental program both in simulant and in prototypic materials.
