Organization / Localization: KTH-NPS Facility Description: Metallic and Oxidic simulant melt spreading in dry and wet cavity conditions. The melt delivery is directly on the substrate eliminating jet and melt disintegraion. Test Identification: CoSMUS01_DM, CoSMUS02_WM, CoSMUS03_DO, CoSMUS04_WO, CoSMUS05_WO SA-Related Topics / Phenomena:Corium spreading in containment cavity with (a) dry condition, and (b) shallow pool of coolant Measured Parameters: Melt spreading dynamics, spreading area, melt delivery rate, melt-substrate interface temperature, melt temperature Modelling: Melt spreading area, cooling of melt Simulation Code: MELTSPREAD; MPS; MSPREAD Experimental Research Program: ROSAU programm supported by SSM Link to PIRT:
