Experimental facilities play a central role in reactor safety research for both design basis and severe accidents (SA). They are key to demonstrate the effectiveness and appropriateness of specific safety features of reactor designs and providing data for the validation of different models implemented in numerical tools used for safety demonstration. Hence, a well-designed and equipped experimental infrastructures in Europe is a fundamental pillar of European roadmap on reactor safety research. One objective of the EU SEAKNOT (Severe Accident research and KNOwledge management) project, is the analysis and mapping of European severe accident research facilities currently under operation. The responses to a questionnaire sent to European institutions were evaluated and the information collected about each facility was synthesized covering different issues such as age, design features, main phenomena addressed by latest research programs, including advanced technologies like Advanced Technology Fuels (ATFs) and Small Modular Reactors (SMRs). The extensive review of the collected information allowed the identification of critical conditions (human resources; preservation and enhancement of experimental competences, etc. that might jeopardize the current and forthcoming European experimental capabilities for severe accident research, according to the Severe Accident roadmap that is being built in SEAKNOT. This paper describes the methodology and major outcomes of this analysis.
