The Fukushima-Daiichi accidents in 2011 underlined the importance of severe accident management SAM including external events in nuclear power plants NPP and the need of implementing efficient mitigation strategies. To this end the Euratom work programmes for 2012 and 2013 was focused on nuclear safety in particular on the management of a possible severe accident at the European level. Relying upon the outcomes of the successful Euratom SARNET and SARNET2 projects new projects were launched addressing the highest priority issues aimed at reducing the uncertainties still affecting the main phenomena. Among them PASSAM and IVMR project led by IRSN ALISA and SAFEST projects led by KIT CESAM led by GRS and sCO2-HeRO lead by the University of Duisburg-Essen. The aim of the present paper is to give an overview on the main outcomes of these projects. 1 Introduction understanding the possible accident scenarios and related phenomena and contributes to improve safety .
