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...
Simultaneous dissolution of UO_2 and ZrO_2 by molten zircaloy. New experiments and modelling
This report summarises the Tasks WP2.1 and WP7.3 of the COLOSS project (core loss during severe accident) within the 5"t"h Framework Programme of EU. The experimental task WP2.1 was performed during 2000-2002 at the RIAR (Dimitrovgrad, Russia) in collaboration with Forschungszentrum Karlsruhe. Whereas RIAR acted as a subcontractor to JRC/IE (Joint ...
Investigation into the safety case of the MEGAPIE target in the spallation neutron source SINQ Pressure development in t...
The MEGAPIE target is being developed as liquid metal target for the Spallation Neutro Source SINQ at the Paul Scherrer Institute at Villigen, Switzerland. The present report analyses the hypothetical accident 'failure of the beam windows of target and safety hull.' During such an accident, the liquid potassium-bismuth alloy from the target would c...

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...
