Overview of Severe Accident Research Activities at the Karlsruhe Institute of Technology
Karlsruhe Institute of Technology (KIT) has a profound knowledge and experience in R&D of nuclear reactor safety and in national and international co-operation. It has a long experience in performing the large-and small-scale experiments in the specific fields of core damage initiation and progression such as the in-vessel and ex-vessel melt progression phenomena and hydrogen behaviour in the containment. A unique combination of facilities and expertise is available at the KIT. The expertise is maintained by participating in collaborative research with laboratories in the EU and other countries. It is considered as a powerful internationally-recognized centre of reference for nuclear research. The aspects of reactor safety and safety of nuclear waste disposal are coordinated by the Programme of Nuclear Safety Research (NUKLEAR). The research activities in the severe accidents domain are concentrated on the in-and ex-vessel core melt behaviour. The overall objective is to investigate core melt scenarios from the beginning of core degradation to melt formation and relocation in the vessel, possible melt dispersion to the reactor cavity and to the containment, and finally hydrogen-related phenomena in severe accidents. The experiments are designed to be complementary to other European facilities and experimental platforms such as CODEX, VULCANO or PLINIUS to form a coherent European nuclear experimental network. They contribute to a better understanding of the core melt sequences and thus improve safety of existing and, in the long-term, of future reactors by severe accident mitigation measures and by safety installations where required. Experimental programmes are part of the SARNET2 and LACOMECO projects of the 7th EU Framework Programme and the results of the experiments are being used for the validation of codes applied for safety assessment and planning of accident mitigation concepts, such as ASTEC.
