Thermochemical Modeling of Metal Composition and Its Impact on the Molten Corium–Concrete Interaction: New Insights with Sensitivity Analysis

Abstract: The characterization of molten corium–concrete interaction (MCCI) has increasingly become a cause of concern because, in the case of a severe nuclear accident, the core could meltdown and release radiation into the environment. The objective of this study was to determine the thermochemical impact of metal content in the corium and analyze the effect of corium metal content on ablation depth, corium temperature, its viscosity and surface heat flux, and production of hydrogen, carbon monoxide, and carbon dioxid… Show more

“…Farmer [4] suggested different correlations to determine the conductivity of concrete within the bounds of 373 to 1073 K; above this limit their suggestion is to use a constant value. However, the corium temperature due to its composition and metal content is in the range of 1200-3000 K [14], far above this range specified by Farmer [4]. Therefore, it is important to investigate different thermal conductivities of concrete to understand the MCCI response.…”

“…Different models and/or simulators have been developed in the past by a number of scientists; Bradley et al, [5] developed CORCON-Mod3, MEDICIS and MAAP were modelled by Crange et al, [10], SOCRAT was developed by Bolshov and Strizhov [11], Polidoro et al, [12] modeled CORIUM-2D and Farmer [4] developed CORQUENCH. Using CORQUENCH, Khurshid et al, [13] and [14] analyzed different parameters affecting concrete ablation. All of these are system level codes which are all generally 1-D (some simplified two-or three-dimensional versions also exist).…”
