European view on severe accidents research
No full textSevere accident with core meltdown is a threat to the containment integrity. As Chernobyl and Fukushima accidents demonstrate, significant release of radioactive products into the environment can cause severe consequences both for people's health and the country's economy. Severe accidents are the focus of considerable research involving substantial human and financial resources worldwide. The research field encompasses too many challenging phenomena, complicated by high temperatures and presence of radioactive materials.
No individual country has sufficient resources to address all important phenomena within the framework of a national research programme, therefore optimised use of recourses and the collaboration at European and international level is 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 to improve safety of existing and, in the long-term, of future reactors
Status and perspectives of SARNET network
No full text43 organisations (research, universities, industry, utilities, safety authorities and TSO) from 22 countries network their capabilities for R&D on
Severe Accidents (SA) in SARNET (Severe Accident Research NETwork of excellence) in the EC FP7 for 4 years from April 2009. The overall work
represents about 40 persons per year (230 researchers and 20 PhD students). A 43rd partner is currently joining the network: BARC (India).

Current Status of NUGENIA-TA2: Severe Accidents
No full textThe SARNET network (Severe Accident NETwork of excellence) was co-funded by EC from 2004 to 2013 in FP6-FP7 and then integrated in NUGENIA and the main network activities are continuing in the NUGENIA Technical Area N°2. As of Dec. 2018, TA2 coordination by CIEMAT was approved by NUGENIA Excom. This paper is aimed at giving an update of TA2, with particular emphasis on recent actions and plans

The Severe Accident Phenomenology Short Course (SAP): 12 years of excellence for dissemination of Severe Accident knowledge at international level
No full textThe last course Severe Accident Phenomenology (SAP) has been held at Stockholm (KTH) in 2015 (July 6th-10th) in the frame of the NUGENIA Technical Area N°2/SARNET on “Severe accidents”. This 1-week course was jointly organized by KTH, CEA, IRSN and University of Pisa and has been hosted by KTH at Stockholm. This is the 6th course since the start of SARNET in 2004. This course was a success showing that the European Network of Excellence SARNET was really the leader for the dissemination of Severe Accident knowledge at international level: 74 participants from Europe, Asia and South-America have been present. The objective of this course is to train Master-PhD students, young engineers and researchers recently involved in severe accidents in nuclear power plants (NPP).
The SAP has evolved from the first course in 2006 till 2015: different important topics for SA phenomenology, progression and mitigation in current water-cooled Gen.II and III NPP, but also the different design solutions in Gen.III have been taught. For the two last sessions (2013 and 2015) new lectures have been given on Fukushima-Daiichi severe accidents and current situation.
The next course will be held in 2018 in Madrid with the support of CIEMAT and Madrid University. A special focus will be developed on recent knowledge gained on Fukushima-aiichi severe accidents
Severe accident research in Europe: SARNET network from Euratom to NUGENIA
No full textSARNET (Severe Accident Research Network) has been set up under the aegis of the Framework Programmes of the European Commission from 2004 to 2013 and under the IRSN coordination to perform R&D on severe accidents in water-cooled nuclear power plants. The network self-sustainability was achieved through integration mid-2013 in the NUGENIA European association devoted to R&D on fission technology of Generation II and III. The SARNET activities continue in the Technical Area “Severe accidents” through technical workshops, ranking of R&D priorities, improvements of severe accident codes, ERMSAR international conferences, and education and training courses.
Six technical domains are addressed in this Technical Area: in-vessel corium/debris coolability, ex-vessel corium interactions and coolability, containment behaviour, including hydrogen risk, source term released to the environment, impact of severe accidents on the environment and emergency management, and severe accident scenarios.
The ranking of research priorities in the NUGENIA R&D roadmap that was published in 2015 underlined the need to focus efforts in the next years on the improvement of prevention of severe accidents and on the mitigation of their consequences, as highlighted by the Fukushima Dai-ichi accidents. Several current or soon starting projects on mitigation of severe accident consequences in Euratom or NUGENIA frame are shortly described in this paper
