- After four and a half years of operation in the frame of the 6th Framework Programme (FP6) of the European Commission, SARNET (Severe Accidents Research NETwork of excellence) continues in the FP7 (project named SARNET2) from April 2009 for 4 years. Forty-one organisations from 21 countries network their capacities of research in order to resolve the most important remaining uncertainties and safety issues on severe accidents (SA) in existing and future water-cooled nuclear power plants (NPPs). It includes a large majority of the Europeanactors involved in SA research plus a few non-European important ones. The objective is to perform the common research programmes that have been defined in the network first phase and to continue to improve the common computer tools and methodologies for NPP safety assessment. It will consolidate the sustainable integration of the European SA research capacities. These research programmes concern essentially the six highest priority safety issues that were identified after ranking in the first phase of the network: in-vessel core coolability, molten-corium-concrete-interaction, fuel-coolant interaction, hydrogen mixing and combustion in containment, impact of oxidising conditions on source term, and iodine chemistry. The Joint Programme of Activities includes the following main tasks: Performing new experiments on the above mentioned issues andjointly analysing their results in order to elaborate a common understanding of the concerned physical phenomena; Continuing the development and assessment of the ASTEC integral computer code (jointly developed by IRSN and GRS to predict the NPP behaviour during a postulated SA), which capitalizes in terms of models the knowledge produced in the network. In particular efforts are being extended to its applicability to BWR and CANDU NPP types; Continuing the storage of the SA experimental results in a scientific database, based on the STRESA JRC tool; Promoting educational and training courses, ERMSAR (European Review Meeting on Severe Accident Research) international conferences (to be held once a year) and mobility of young researchers or students between the various European organisations. Some R&D results obtained in the first year of the project are presented, in particular: the VULCANO experiment done in CEA mid-2009 on molten-core-corium-interaction, and the release of the first version of the new ASTEC V2 series.

Konferensbidrag (refereegranskat)abstract
- Fifty-one organisations network in SARNET (Severe Accident Research NETwork of Excellence) their research capacities in order to resolve the most important pending issues for enhancing, with regard to Severe Accidents (SA). the safety of existing and future Nuclear Power Plants (NPPs). This project. co-funded by the European Commission (EC) under the 6th Framework Programme, has been defined in order to optimise the use of the available means and to constitute sustainable research groups in the European Union. SARNET tackles the fragmentation that may exist between the different national R&D programmes, in defining common research programmes and developing common computer tools and methodologies for safety assessment. SARNET comprises most of the organisations involved in SA research in Europe, plus Canada. To reach these objectives, all the organisations networked in SARNET contributed to a joint Programme of Activities, which consisted of: Implementation of an advanced communication tool for accessing all project information, fostering exchange of information, and managing documents: Harmonization and re-orientation of the research programmes, and definition of new ones; Analysis of the experimental results provided by research programmes in order to elaborate a common understanding of relevant phenomena; Development of the ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA), which capitalizes in terms of physical models the knowledge produced within SARNET; Development of Scientific Databases in which all the results of research programmes are stored in a common format (DATANET); Development of a common methodology for Probabilistic Safety Assessment of NPPs; Development of short courses and writing a textbook on Severe Accidents for students and researchers; Promotion of personnel mobility amongst various European organisations. This paper presents the major achievements after four and a half years of operation of the network, in terms of knowledge gained, of improvement of the ASTEC reference code, of dissemination of results and of integration of the research programmes conducted by the various partners. After this first period (2004-2008), co-funded by the EC, a further contract SARNET2 with the EC for the next four years started in April 2009 as part of the 7th Framework Programme. During this period, the networking activities will focus mainly on the remaining pending issues as determined during the first period, experimental activities will be directly included in the common work and the network will evolve toward complete self-sustainability. The bases for such an evolution are presented in the last part of the paper.

Tidskriftsartikel (refereegranskat)abstract
- In order to optimise the use of the available means and to constitute sustainable research groups in the European Union, the Severe Accident Research NETwork of Excellence (SARNET) has gathered, between 2004 and 2008, 51 organizations representing most of the actors involved in severe accident (SA) research in Europe plus Canada. This project was co-funded by the European Commission (EC) under the 6th Euratom Framework Programme. Its objective was to resolve the most important pending issues for enhancing, in regard of SA, the safety of existing and future nuclear power plants (NPPs). SARNET tackled the fragmentation that existed between the national R&D programmes, in defining common research programmes and developing common computer codes and methodologies for safety assessment. The Joint Programme of Activities consisted in:Implementing an advanced communication tool for accessing all project information, fostering exchange of information, and managing documents;Harmonizing and re-orienting the research programmes, and defining new ones;Analyzing the experimental results provided by research programmes in order to elaborate a common understanding of relevant phenomena;Developing the ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA) by capitalizing in terms of physical models the knowledge produced within SARNET;Developing scientific databases, in which the results of research experimental programmes are stored in a common format;Developing a common methodology for probabilistic safety assessment of NPPs;Developing short courses and writing a text book on severe accidents for students and researchers;Promoting personnel mobility amongst various European organizations. This paper presents the major achievements after four and a half years of operation of the network, in terms of knowledge gained, of improvements of the ASTEC reference code, of dissemination of results and of integration of the research programmes conducted by the various partners. Most initial objectives were reached but the continuation of the SARNET network, co-funded by EC in the 7th Framework Programme (SARNET2 project that started in April 2009 for 4 years), will consolidate the first assets and focus mainly on the highest priority pending issues as determined during the first period. The objective will be also to make the network evolve towards a complete self-sustainability.
