The CEA is the French Alternative Energies and Atomic Energy Commission (Commissariat à l'Energie Atomique et aux Energies Alternatives), a public body established in October 1945. As leader in research, development and innovation, the CEA mission statement has two main objectives: to become the leading technological research organisation in Europe and to ensure that the nuclear deterrent remains effective in the future. The CEA is active in four main areas: low-carbon energies, defense and security, information technologies and health technologies. In each of these fields, the CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research. The total CEA workforce consisted of about 15,838 employees, 1,556 PhD students and 293 post-docs.
The CEA implements an extremely proactive policy on working with its European partners, which is manifested in its highly-committed involvement in a series of research and development framework programs (FP). At the end of 2011 the CEA was involved, within the framework of FP7, in more than 530 projects and acts as coordinator for 70 of these. CEA was thus ranked in the 4th position among European research institutes with a success rate for European projects of 33%. Huge funding for research and development permeate CEA’s research programmes. Within the framework of FP7 55 billion of euros were distributed between 2007 and 2013.
CEA is also involved in Marie-Curie Cofund projects and Eurotalents programme. The CEA has also been heavily involved in several European infrastructures such as Jules Horowitz reactor, Prace, Spiral2 and Prins for nanotechnologies.
Different units of the Nuclear energy division with specific relevant expertise are involved in SOTERIA:
|Dr Christian ROBERTSON, PhD in Materials Science
C. Robertson has been involved with the observation and modelling of grain size plasticity (µm scale) in metallic materials for more than 15 years. This research involves observations using various techniques (SEM, TEM, AFM) and Dislocation Dynamics numerical simulations. This combined approach is applied to radiation-induced degradation of the mechanical properties of structural materials, with a view to improve component design and maintenance engineering tools. The above-described activities has been undertaken in the frame of International collaboration agreements including: Eurofusion-IREMEV, PERFORM60, Indo-French Cooperation Agreements on Basic Research, etc... C. Robertson also collaborates with industrial partners and many French and foreign institutes such as EDF R&D, AREVA, INP Grenoble, IFCEN (China), Czech Academy of Sciences (Brno). He is now acting as the coordinator of the SOTERIA project and directly contributes to WP2 and WP5 tasks.
|Dr T. JOURDAN, PhD in Material Science
Thomas Jourdan has been involved in the modelling of radiation effects in metals for more than 5 years. He is responsible for the development of the cluster dynamics code CRESCENDO in collaboration with EDF R&D. He works in close relationship with experts in experimental characterisation (microstructures, mechanical properties) and modelling at the atomic scale. He collaborates with industrial partners and many French and foreign institutes such as EDF R&D, AREVA, UMET at University of Lille, CSNSM at University of Orsay – Paris XI, University of Alicante (Spain), Beihang University (China). He has participated to several French and European research projects: ANR Project ParMat (development of efficient kinetic simulation tools), ANR Project HSynThEx (role of gas atoms on the microstructure of iron-based alloys), ANR Project CoIrrHeSim (swelling of austenitic steels), FP7 projects PERFORM 60 (creep in austenitic steels) and MOIRA (creep in ferritic steels). In SOTERIA he is one of the main people involved in the development of CRESCENDO in close collaboration with research institutes and industrial partners (EDF R&D).
|Dr. Benoit TANGUY, Senior Expert Materials Science, Habilitation, PhD in Material Science (Ecole des Mines de Paris)
Benoit Tanguy has been involved in fracture mechanics, behavior and fracture modelling of metallic materials and structural integrity assessment for more than 12 years. After a Professor-assistant position at Ecole des Mines de Paris, he joined CEA in 2007 where he is especially involved in studies related to pressure vessel steels and internals. He is a well-recognised specialist in materials science and the leader of CEA RPV and Internals Ageing project. He collaborates with many foreign and french institutes such as EDF R&D, CNRS, University of Toulouse in France, IWM in Germany, Joszef Stefan Institute in Slovenia. He participates to several european and french research projects (PERFORM-60, NESK-7). In SOTERIA he is involved in the experimental characterisation and mechanical behavior and fracture modeling of internals. He participates in the project management as expert as well.
|Dr Ludovic VINCENT, Research engineer, PhD in Mechanics of Materials (2002)
Ludovic Vincent has been involved in High cycle fatigue and Thermal Fatigue of Austenitic Stainless Steels as well as in Crystal Plasticity Finite Element Modelling applied to the Brittle Fracture of Reactor Pressure Vessel Steels for more than 10 years. He mainly focuses on the implantation of physically-based crystal plasticity constitutive laws into Finite Element codes and run Crystal Plasticity Finite Element simulations of bainitic aggregates in order to feed models of Local Approach to Failure with the distribution of local stress fields. He collaborates with many foreign and French institutes such as EdF (France), AREVA (France and Germany), VTT (Finland). He participates to many European and French research projects (PERFECT, PERFORM 60, ANR AFGRAP). In SOTERIA he is acting as the task leader for task 5.2.
|Dr. Bernard MARINI, Senior expert in Material Science, PhD Material Science (Ecole des Mines de Paris), male. Chief scientist in Material Science
He works since 30 years on the impact of ageing on the materials of the primary and secondary circuits of nuclear power plants. He is a well-recognised specialist in mechanical behaviour and fracture of materials. He collaborates with a lot of foreign and French research institutes as well as with industrial partners. Bernard Marini was strongly involved in PERFECT (FP6), PERFORM 60 and LONGLIFE projects (FP7). In SOTERIA he is involved in several scientific tasks as senior expert in radiation-induced ageing of RPV and internals steels. He also takes part in project management.
|Dr Laure MARTINELLI, Research Engineer, PhD Analytical Chemistry (Université P&M Curie), Engineer Diploma material science (Ecole des Mines de Paris)
Laure Martinelli is a well-recognised specialist of high temperature corrosion and corrosion in heavy liquid alloys. She works in close relationship with experts in experimental characterisation (microstructures, mechanical properties, oxidation process) and modelling. She collaborates with industrial partners and many French and foreign institutes such as EDF R&D, AREVA, CNRS. She has participated to several French and European research projects. In SOTERIA she is one of the main people involved in the development of EKINOX.
