Organization / Localization: KTH-NPS Facility Description: The facility is composed of a 45-kW medium frequency (up to 30kHz)induction furnace (IF) for melt generation, melt delivery funnel, andcoolant tank with a glass window for visual imaging of transientpre-mixing. Test Identification: SAFEST-A22 SA-Related Topics / Phenomena:Oxidic simulant melt fragmentation and debris bed formation in deep water with installed rod Measured Parameters: Debris bed 3D scanning, agglomeration fraction as pool depth function, particle size distribution as pool depth function, debris bed porosity estimate Modelling: Melt jet breakup Simulation Code: Experimental Research Program: EU SAFEST Link to PIRT:
