CEA is a science and engineering research institution funded by the French government and industrial contractors. It is organized in four research and development sectors: nuclear energy (DEN), technological research (DRT), fundamental research (DSM and DSV) and defence (DAM).

The nuclear energy programmes are devoted to the support for nuclear power stations in operation, design of systems for the future, studies for waste management and dismantling of obsolete installations. CEA has recognised and long scientific and technological experience in the field of nuclear safety and nuclear data. The synergy between its different components allows CEA covering all the aspects of nuclear data: fundamental measurements, theory, integral measurements, evaluation, simulation code development and validation.


Nuclear Energy Division (DEN)

Relevant experience

In the area of nuclear energy, the research is primarily being conducted by the teams of the DEN. Within DEN, the Innovation and Nuclear Support Division (DISN) is the Program Division in charge of the strategy, development and follow-up of basic research, simulation tools and associated experimental facilities which are necessary as a support for present and future nuclear power plants. One of them is the Simulation Program of DEN which aims at improving the legacy codes (such as APOLLO, CRONOS, ERANOS, TRIPOLI, CATHARE, FLICA...) and developing a new generation of codes. This program includes the development of predictive physical models, advanced numerical techniques, new software architectures, experimental validation of the calculations and basis data improvement. In the neutronic field of this Simulation Program, an important amount of work has been done, and is on going, to provide improved Nuclear Data to JEFF community and to developed new evaluation code CONRAD. In the same time several dedicated integral experiments are performed in the EOLE, MINERVE and MASURCA facilities to assess the neutronic behaviours of different types of reactor cores: PWR (Pressurized Water Reactor), BWR (Boiled Water Reactor), SFR (Sodium cooled Fast Reactor), ...

Scientific and technical personnel involved

  • P. Leconte: In charge of physical design and in the interpretation of integral experiments in EOLE & MINERVE reactors. Will be WP12 leader.
  • D. Bernard: Expert in Nuclear Data as well as in the interpretation of integral experiments. Former WP3 leader in ANDES. Will be involved in WP8.
  • C. De Saint Jean: Head of the laboratory LEPh in CEA/DEN. Is in charge of the development of code CONRAD.
  • G. Noguere: Head of the Nuclear Data Project for CEA/DEN and Nuclear Data Expert in Evaluation. Will be part of WP8 and WP9.

Physical Sciences Division (DSM)

The division conducts fundamental research in the fields of energy, climate, fundamental laws of the Universe, condensed matter and nanoscience. The Institut de Recherches sur les lois Fondamentales de l'Univers (IRFU) is responsible for experimental and theoretical research in nuclear and particle physics, astrophysics, and instrumentation.

Relevant experience

The nuclear physics division (SPhN) plays a leading role in developing instrumentation and carrying out research at several European facilities. It conducts a basic research program on nuclear reactions involving neutrons, photons and protons over a wide energy range. SPhN groups have also recognised experience in the modelling of nuclear reactions, validation and benchmarking of reaction models for applications to nuclear energy, transmutation of nuclear waste, non-proliferation, non-destructive characterization of waste packages, design-decommissioning of nuclear installations, nuclear medicine, ...

  • S. Leray: Directeur de Recherche CEA. Leader of the SPALLATION group working on experiments, modelling and validation in spallation physics. Will be the coordinator of WP2 and WP11. She has participated in the FP5-HINDAS project and was WP leader in FP6-EUROTRANS/NUDATRA and FP7-ANDES.
  • J.C. David: Physicist working in the Spallation group. Specialist in model validation and high-energy transport codes. He was Task leader in ANDES and will be responsible for Tasks 11.3 and 11.5.

He participated earlier as Task leader in FP5-n-TOF-ND-ADS, FP6-EUROTRANS/NUDATRA and FP7-ANDES project. Will be involved in WP7 and will be responsible for Task 7.4.
  • D. Doré: Experimental nuclear physicist working on fission yield measurements. Leader of the FALSTAFF project in SPhN. Will be responsible for Task 8.5.

Direction des Applications Militaires or Division of Military Applications (DAM)

Relevant experience

DAM is primarily involved in defence applications like the French Simulation program. The development of the Simulation program relies on extensive modelling of physical processes as well as systematic experimental validation of each of the individual models with laboratory experiments. That effort encompasses the fields of nuclear physics and nuclear data which are relevant to the CHANDA project as it was for the HINDAS, EUROTRANS/NUDATRA, CANDIDE, EFNUDAT, ERINDA and ANDES projects. CEA-DAM also provides evaluated nuclear data files to the JEFF project jointly with CEA-DEN and collaborates with NRG on the development of the TALYS nuclear reaction code.

The section of CEA-DAM involved in CHANDA is the Service de Physique Nucléaire of the CEA-DIF (DAM Ile-de-France). Read  references Nuclear Physics News Vol.18, No 4, p. 5, (2008), and European Physics Journal A 48, 113 (2012).
