Organization / Localization: KTH-NPS Facility Description: It consists of an interaction chamber, an induction melt furnace, an external trigger system, an operational control system, and data acquisition and visualization systems. The test section is a rectangular tank (180x130x250mm) with 4 view windows (70x150x24mm) with a 1kW immersion heater. Test Identification: MISTEE-Al SA-Related Topics / Phenomena:Spontaneous steam explosion. Melt fragmentation. Measured Parameters: Steam explosion impulse. Melt fragmentaiton dynamic. Modelling: Simulation Code: Experimental Research Program: (i) EU SAFEST; (ii) National program "Accident Phenomena of Risk Importance" (APRI) supported by consortium of SSM and NPPs in Sweden Link to PIRT:
