HTCM - Investigations on Heat Transfer Phenomena in Prototypic Core Melt Pools

HTCM-Body after the experiment

Of particular interest to the investigation are the thermal and thermo-chemical interactions between the generated corium-melt at temperatures above 2000°C and generic corecatcher structures. The focal point of the investigations is here the determination of the time dependent heat flow in the used special sample structures and the time dependent formation of a crust. From the rate of temperature increase measured in the sample structure or in the substrate, the solution of the inverse heat conduction problem (IHCP) allows to calculate the surface temperature and the heat current density as a function of time.
