The objective of the workshop is the presentation and discussion of recent experimental results in the field of reflood of an overheated reactor core and related problems as well as the status of the modelling activities on quenching in the various code systems. Results of post-test examinations of the air ingress experiment QUENCH-16 and of the QUENCH-LOCA-1 test as well as the status of the preparations of the QUENCH-DEBRIS experiment will be presented at the first day of the workshop. Wednesday is reserved for presentations on modelling and code application and will be finished with an excursion of various large-scale experiments and the nuclear museum at KIT Campus North and invited dinner. Thursday will be devoted to recent studies concerning high-temperature behaviour and oxidation of core materials under severe accident conditions. Furthermore, the status of other international programmes connected to the KIT QUENCH programme is planned to be presented.
