The Status Report on Ex-Vessel Steam Explosion (EVSE) summarises the significant progress made in the field of Fuel Coolant Interaction/Steam Explosion (FCI/SE) knowledge during these last ten years, especially in the framework of the OECD/SERENA-Phase 2 program (2007-2012).
 
Key phenomena for steam explosions have been ranked for their knowledge base and possible consequences for the containment building. From this ranking, it can be stated that jet orientation and fragmentation, triggering, solidification and oxidation phenomena are considered to have limited knowledge, but also high importance on SE energetics.
