Test and simulation results of LIVE-L4 + LIVE-L5L . (KIT Scientific Reports ; 7593)

The objective of the LIVE program is to study the core melt phenomena during the late phase of core melt progression in the RPV both experimentally in large-scale 3D geometry and with CFD simulation. LIVE-L4 and LIVE-L5L experiments investigate the transient and steady state behaviors of the molten pool and the crust at the melt/vessel wall interface influenced by the several melt relocation numbers and different heat generation rate during external cooling. The melt pool behaviour and crust thickness in L4 test are calculated by CONV-code.
