Melt cooling by bottom flooding: the experiment CometPC-H4 and -H5 Ex-vessel core melt stabilization research
The large-scale experiments CometPC-H4 and -H5 investigate cooling of simulated corium melts by flooding the melt from the bottom through layers of porous, water filled concrete. Both experiments use 800 kg of oxidic and metallic melts, initial temperature from 1800 to 1900 C, with simulation of nuclear decay heat by inductive heating with 300 KW t...
KAPOOL experiments on melt-through of a metal plate by an overlying melt pool
In the event of a hypothetical severe accident in a Light Water Reactor (LWR) it is possible that the core melts and relocates to the lower head of the reactor pressure vessel (RPV). If the severe accident management measures are not successful, the RPV can fail and the core melt is discharged onto the basement of the containment. To prevent a sign...

Melt dispersion and direct containment heating (DCH) experiments in the DISCO-H test facility
The DISCO-H Test Facility at Forschungszentrum Karlsruhe was set up to perform scaled experiments that simulate melt ejection scenarios under low system pressure in Severe Accidents in Pressurized Water Reactors (PWR). These experiments are designed to investigate the fluid-dynamic, thermal and chemical processes during melt ejection out of a breac...

The CometPC-H3 experiment was performed to investigate melt cooling by water addition to the bottom of the melt. The experiment was performed with a melt mass of 800 kg, 50% metal and 50% oxide, and 300 kW typical decay heat were simulated in the melt. As this was the first experiment after repair of the induction coil, attention was given to avoid...
