The European Commission, in the framework of the SAFEST project (Severe Accident Facilities for Europe Safety Targets), co-finances the selected experiments in the area of ​​severe accidents in nuclear power plants at different experimental facilities in Europe. The SAFEST project  includes also the Steam Explosion Stratified (SES) facility, located at the Royal Institute of Technology (KTH) in Sweden, and is intended to investigate steam explosions in stratified conditions. A steam explosion can occur during a severe accident in a nuclear power plant when a molten corrium comes in contact with the cooling water.

Under the joint leadership of dr. Matjaž Leskovar from the Jožef Stefan Institute (JSI) Reactor Engineering Divison and dr. Erik De Malmazet of the Électricité de France (EDF) from France a group of experts from the IJS, EDF, the Commissariat à l'Energie Atomique et aux Energies Alternatives (CEA) and the Institute of Radioprotection et de Sûreté Nucléaire (IRSN) from France and the Institute for Nuclear Technology and Energy Systems (IKE) from Germany developed an experiment on a steam explosion on the SES device, which was successfully executed in May 2016.

At the end of the SAFEST project, the CEA organized the final SAFEST seminar on experimental research in the field of severe accidents, which was held from 10-12 December 2018 in Cadarache, France, with about 40 participants. The seminar consisted of four sections: General Topics, Problem of melted corium in the reactor vessel, Problem of melted corium outside the reactor vessel, Other topics. At the seminar participants presented the results of the project and plans for the future.

The seminar was attended by dr. Matjaz Leskovar from the IJS who had a presentation with the title: E. De Malmazet (EDF), M. Leskovar (IJS) et al., Stratified Steam Explosion Phenomena: SAFEST SES-S1 test results and analysis.
