Large Scale Separate Effects Tests on Hydrogen Combustion during Direct Containment Heating Events (KIT Scientific Reports ; 7663)

Beschreibung

Combustion codes were applied to reproduce the experimental data from tests which investigate high pressure melt ejection (HPME) and direct containment heating (DCH) issue. The code calculations revealed shortcomings of the existing models which made an application of the code for reactor calculations unfeasible because of the required up-scaling. Combustion and heat loss models need further improvements. However, data from experiments at a single scale are not sufficient to reach this goal.
