The Nuclear Energy Agency (NEA) of the Organization for Economic Co-operation and Development (OECD) has, since 2002, sponsored Melt Coolability and Concrete Interactions (MCCI) co-operative project in two phases to investigate ex-vessel melt coolability and concrete interaction by means of separate-effects tests and large scale integral tests carried out at the Argonne National Laboratory (ANL). A working group was established in April 2012 within the frame of the Working Group on Accident Management and Analysis (WGAMA) to address the preparation of a state-of-the-art report on melt coolability and core concrete interactions that captures the last thirty years of international research results. This paper synthesizes this new state of the art report on molten core concrete interaction.
