“…In 2004, the European Commission (EC) judged necessary to better coordinate the national efforts in Europe to optimise the use of the available expertise and the experimental facilities in view of resolving the remaining issues for enhancing the safety of existing and future NPPs. This led to launching SARNET (Albiol et al, 2008;Micaelli et al, 2005) in the framework of the 6th EC Framework Programme (FP6), coordinated by IRSN, gathering 55 actors, mostly European ones plus a few out of Europe, on severe accident R&D. One of the main outcomes was the identification of the highest priority severe accident issues still to be solved that helped to build a second phase of the network again supported by EC in the FP7 under the project name "SARNET2" (www.sar-net.eu) and coordinated by IRSN between April 2009 andMarch 2013. After the description of the network structure and tasks in Section 2, Section 3 summarizes the main technical outcomes of the following R&D topics: in-and ex-vessel corium/debris coolability, molten-core-concrete-interaction (MCCI), containment issues and source term. Sections 4 and 5 present, respectively, the activities on the ASTEC IRSN-GRS integral code and on spreading of knowledge.…”

The SARNET network (Severe Accident Research NETwork of excellence), co-funded by the European Commission from 2004 to 2013, has allowed to significantly improve the knowledge on severe accidents and to disseminate it through courses and ERMSAR conferences. The major investigated topics, involving more than 250 researchers from 22 countries, were in- and ex-vessel corium/debris coolability, molten-core–concrete-interaction, steam explosion, hydrogen combustion and mitigation in containment, impact of oxidising conditions on source term, and iodine chemistry. The ranking of the high priority issues was updated to account for the results of recent international research and for the impact of Fukushima nuclear accidents in Japan. In addition, the ASTEC integral code was further developed to capitalize the new knowledge. The network has reached self-sustainability by integration in mid-2013 into the NUGENIA Association. The main activities and outcomes of the network are presented

Corium Experimental Thermodynamics: A Review and Some Perspectives

More than 30 years ago a specialist meeting was held at Joint Research Center Ispra (Italy) from 15 to 17 January 1990 to review the current understanding of chemistry during severe accidents in light water reactors (LWR). Let us consider that, at the end of the 1980s, thermodynamics introduced in the severe accident codes was really poor. Only some equilibrium constants for a few simple reactions between stoichiometric compounds were used as well as some simple correlations giving estimates of solidus and liquidus temperatures. In the same time, the CALPHAD method was developed and was full of promise to approximate the thermodynamic properties of a complex thermochemical system by the way of a critical assessment of experimental data, a definition of a simple physical model and an optimisation procedure to define the values of the model parameters. It was evident that a nuclear thermodynamic database had to be developed with that new technique to obtain quite rapidly prominent progress in the knowledge of thermochemistry in the severe accident research area. Discussions focused on the important chemical phenomena that could occur across the wide range of conditions of a damaged nuclear plant. The most pressing need for improved chemical models is identified with condensed phase mixtures to model the corium progression. This paper reviews more than 30 years of experimental data production in the field of corium thermodynamics. This work has been conducted through multiple international programs (EURATOM, ISTC, OECD) as well as through more specific studies conducted at the national scale. This research has been capitalised in specific databases such as NUCLEA and TAF-ID, databases developed at IRSN and at CEA, respectively, and are now used in degradation models of the severe accident simulation codes. This research is presented in this paper. In the conclusion, we outline the research perspectives that need to be considered in order to address today’s and tomorrow’s issues.

“…Facing the increasing reduction of the national budgets on SA researches, in 2003 EC judged necessary a better coordination of the single national efforts in this field to preserve and optimise the use of the available expertise and of the experimental facilities, in order to resolve the remaining "open issues" for enhancing the safety of existing and future NPPs. In April 2004, 51 worldwide organisations involved in R&D on SA, including research organisations, safety authorities, technical safety organisations (TSO), industries, utilities, and universities, decided to network together in SARNET, in the framework of the EC FP6, linking their capacities of research in the SA area in a consolidated manner [3] in a network of excellence, that is, an instrument for strengthening excellence by tackling the fragmentation of the European research, where the main deliverable is a durable structuring and shaping of the way that research is carried out on the topic of the network. A second phase of this excellence network (SARNET2) has started in April 2009, again supported by EC during the present FP7, for a duration of 4 years and again under the coordination of the French "Institut de Radioprotection et de Sûreté Nucléaire" (IRSN).…”

The SARNET2 (severe accidents Research NETwork of Excellence) project started in April 2009 for 4 years in the 7th Framework Programme (FP7) of the European Commission (EC), following a similar first project in FP6. Forty-seven organisations from 24 countries network their capacities of research in the severe accident (SA) field inside SARNET to resolve the most important remaining uncertainties and safety issues on SA in water-cooled nuclear power plants (NPPs). The network includes a large majority of the European actors involved in SA research plus a few non-European relevant ones. The “Education and Training” programme in SARNET is a series of actions foreseen in this network for the “spreading of excellence.” It is focused on raising the competence level of Master and Ph.D. students and young researchers engaged in SA research and on organizing information/training courses for NPP staff or regulatory authorities (but also for researchers) interested in SA management procedures.
