Description
One of the main concerns in Tokamak operation is the dust resuspension and fallout in case of LOVA (Loss Of Vacuum Accident) and LOCA (Loss Of Coolant Accident), as the metallic powders contained in the vessel are radioactive and therefore harmful. Furthermore, they can react explosively with the incoming oxygen if the local composition falls inside the flammability interval and if a hot point triggers the reaction.
CFD (Computational Fluid Dynamics) multiphase simulations have been carried out for several pressurisation rates and various inlet points to determine the flow features and the amount of mobilised dust. The numerical simulations results have been compared with experimental data, all the results will be discussed in this work.
