Commissariat à l'Energie Atomique et aux Energies Alternatives (CEA), France

Website: http://www.cea.fr

The Commissariat à l’Energie Atomique (CEA) is a science and engineering research institution, funded by the French Government and industrial contractors. The CEA is organized in four research and development sectors: nuclear energy (DEN), technological research (DRT), fundamental research (DSM and DSV) and defense (DAM). The nuclear energy programs are devoted to the support for nuclear power stations in operation, design of systems for the future (in particular Gen-IV reactors), studies for waste management and dismantling of obsolete installations. CEA has recognized and long scientific and technological experience in the field of 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.

In the area of nuclear energy, the research is primarily being conducted by the teams of the Nuclear Energy Division (DEN). Within DEN, the Simulation and Experimental Tools Division (DSOE) 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 to assess the neutronic behaviors of different types of reactor cores: PWR (Pressurized Water Reactor), BWR (Boiled Water Reactor), SFR (Sodium cooled Fast Reactor), GFR (Gas cooled Fast Reactor) … DSM is the ‘Directorat’ (about 1700 permanent staff) of CEA, involved in various kinds of physics and associated technologies.

DSM, the Physical Sciences Division, conducts fundamental research in the fields of energy, climate, fundamental laws of the Universe, condensed matter and nanoscience. The IRFU (Institut de Recherches sur les lois Fondamentales de l'Univers) is responsible for experimental and theoretical research in nuclear and particle physics, astrophysics, and instrumentation (see also: http://irfu.cea.fr). The nuclear physics division (SPhN) plays a leading role in developing instrumentation and carrying out research at several European facilities. It conducts a program of basic research on nuclear reactions involving neutrons, photons and protons over a wide energy range. SPhN groups have also recognized experience in the modeling 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, designdecommissioning of nuclear installations, nuclear medicine, etc..

CEA key person involved in the MAX project:

Didier URIOT is an accelerator engineer of CEA Saclay (IRFU / SACM). With a degree in electronics, he joined CEA in 1989 in charge of the diagnostics of the accelerator SATURNE. Since 15 years, his main activity is the design of high-power linear accelerators, with special focus on beam dynamics and software developments. He is being involved in the following projects: EUROTRANS, LINAC4, SPL, SNS, IFMIF, SPIRAL2, EURISOL, IPHI.
