Severe Accident Research (SAR)

Research Activities

• Cooling of fuel assmeblies near Critical Heat Flux (CHF)
• Countercurrent flow during hot leg injection by the emergency core cooling system
• Analysis of core melt accidents: Coolabilty of the melt inside the reactor pressure vessel
• Dispersion of the melt to the reactor cavity and containment (DCH)
• Intraction of melt with concrete of the reactor foundation


Methods

Experiments and analysis of transient and steady state single and multi-phase flow
of gas, steam, water, liquid metal and melts up to 2100 °C
