Influence of Concrete Properties on Molten Core-Concrete ...

In this paper, a simulation study is presented that aims to address the influence of sacrificial concrete properties on molten core-concrete interaction (MCCI). In particular, based on the MELCOR Code, the ferrosiliceous concrete used in European Pressurized Water Reactor (EPR) is taken into account with respect to the different ablation enthalpy and Fe2O3 and H2O contents.

[PDF] Molten Core - Concrete Interactions in Nuclear ...

In a hypothetical severe accident in a nuclear power plant, the molten core of the reactor may flow onto the concrete floor of containment building. This would cause a molten core concrete interaction (MCCI), in which the heat transfer from the hot melt to the concrete would cause melting of the concrete. In assessing the safety of nuclear reactors, it is important to know the consequences of ...

At first, the long-term properties of concrete is summerized. The compressive strength increases gradually from one year to 20 years. The strength of core sample is almost same as that of standard curing specimen at the 22nd year. It was confirmed that the compressive strength is sufficiently larger than the specified design strength.
