摘要：

In order to study the interaction between the Molten Corium-Concrete Interaction (MCCI), an MCCI analysis code is developed by coupling the models of corium-concrete heat transfer, concrete pyrolysis, metal oxidation in the melt, corium cooling by top flooding. The code is validated using MACE M3b and OECD/MCCI CCI-3 tests. The calculation results of melt temperature, axial and radial ablation depths, upward heat flux are in good agreement with the experimental measurements. The sensitivity calculation and analysis of decay heat, concrete type and water injection moment are carried out and further verify the rationality of the procedure.
