Commissariat à l’Energie Atomique

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.

Role in the project

Different units of the Nuclear energy division with specific relevant expertise are involved in SOTERIA:

  • Nuclear energy division: DEN/DIR through the programme for Gen2/Gen3 reactors and the programme for basic research in nuclear science and technology is involved at the highest level to contribute to the WP1 in particular to the strategic documents.
  • Departments for Legal Affairs: DEN/DGES and DJC have a vast experience in legal affairs including setting-up of contracts and agreements covering governance, IPR, finances, etc.
  • Departments for European Affairs: DAE and DEN/EA bring their expertise to WP1 on European affairs and link up with EERA, NUGENIA and other European bodies.
  • Department for nuclear materials (DMN): The DMN contributes in particular with the microstructural characterisation and the mechanical testing of ion-implanted or neutron-irradiated materials, the modelling of irradiation effects at different scale and ion-beam irradiation.
    The three research units of DMN are involved in SOTERIA:
    • The Service of Research in Physical Metallurgy (SRMP) contributes to the physics modelling of irradiation damage and dislocation behaviour.
    • The Service of Studies on Irradiated Materials (SEMI) carries out the mechanical and corrosion tests planned on irradiated specimens.
    • The Service of Applied Metallurgical Researches (SRMA) contributes to the microstructural and mechanical aspects of materials involved in different work-packages dealing with flow and fracture behavior prediction.
  • Department for Physico-Chemistry (DPC): The DPC, and more specifically the“Service de Corrosion et du Comportement des Matériaux dans leur Environnement (SCCME)”, contributes to the corrosion studies (IASCC) in WP4 and WP5.

Personnel involved

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).
