Facility Details: CORESA (Zirconia stability against stratified metal-oxide melts)
Organization / Localization: Siempelkamp NT Facility Description: Large-scale experiments investigating the stability of zirconia under a superheated steel layer covered with iron oxide rich melt, the upper surface was heated by gas burners, temperature range up to 2000°C, time up to 14h Test Identification: SA-Related Topics / Phenomena:Stability of zirconia-based material against steel and prototypic corium melts (laboratory and large scale). Measured Parameters: Temperatures, Post test examination (Infiltration, Surface structure) Modelling: Simulation Code: Experimental Research Program: CORESA Consortium (Siempelkamp NT, Battelle, RWTH Aachen, Siemens) / BMFT Link to PIRT: Objective: Validation tests for the former EPR spreading concept with zirconia bottom layer
