Organization / Localization: KTH-NPS Facility Description: Dryout / remelting study of inductively heated debris bed in hemispherical slice geometry (Debris height = 340 mm, Debris radius = 500 mm, Thickness = 30 mm) under water. Debris simulant material: carbon steel and Sn-Bi particles with 1-2 mm diameter. Test Identification: Debris dryout / remelting SA-Related Topics / Phenomena:Debris bed coolability, dryout and remelting under water. Melt relocation in particulate debris bed Measured Parameters: Debris bed temperature, dryout location, incoming water flow, video observation Modelling: Dryout power, dryout location Simulation Code: COCOMO Experimental Research Program: National program "Accident Phenomena of Risk Importance" (APRI) supported by consortium of SSM and NPPs in Sweden, ENSI, CNPE
