Abstract

The HECLA experiments investigate interactions between metallic melt and concrete. They involve pouring of 50 kg of stainless steel into a cylindrical concrete crucible. Three full-scale experiments have already been performed, one with ordinary siliceous concrete and two with hematite-containing concrete, similar to the sacrificial concrete in the EPR reactor pit. The ablation depths have been between 0 and 30 mm. Clear differences between the two concrete types have not been observed. Dramatic effects, e.g. explosive spalling, have not taken place.
