No individual country has sufficient resources to address all severe accident important phenomena within the framework of a national research programme, therefore optimised use of resources and the collaboration at European and international level are very important. Integrating European severe accident research facilities into a pan-European laboratory for severe accident and corium studies and providing resources to other European partners for better understanding of possible accident scenarios and phenomena is necessary in order to improve safety of existing and, in the long-term, of future reactors. SAFEST (Severe Accident Facilities for European Safety Targets) is a European project networking the European corium experimental laboratories with the objective to establish coordination activities, enabling the development of a common vision and of research roadmaps for the next years, and of the management structure to achieve these goals. One of the main objectives is to address and resolve the variety of the remaining severe accident issues related to accident analysis and corium behaviour. The project is a valuable asset for the fulfilment of the severe accident R&D programmes that are being set up after the Fukushima Daiichi accidents and the subsequent European stress tests, addressing both national and European objectives. Roadmaps on European severe accident experimental research for water reactors and for GenIV technologies will be drafted. Joint R&D is conducted to improve the excellence of the SAFEST facilities: this includes measurement of corium physical properties, improvement of instrumentation, consensus on scaling law rationales and cross comparison of material analyses. Joint experimental research is a clear objective in the SAFEST project to provide solutions for stabilization of severe accident and termination of consequences for the current Gen II and III plants. Consequently, the knowledge obtained in SAFEST shall lead to improved severe accident management measures, which are essential for reactor safety. In addition, it will offer competitive advantages for the nuclear industry and contribute to the long-term sustainability of nuclear energy.
