CEA-Thermal Hydraulics CEA-Thermal Hydraulics is a research division within the Commissariat à l'énergie atomique et aux énergies alternatives focused on fluid dynamics, heat transfer, and safety analysis for energy systems. It operates at the intersection of experimental facilities, numerical simulation, and regulatory frameworks, supporting projects in civilian nuclear power, advanced reactor concepts, and thermal management for industry. The division engages with numerous international laboratories, regulatory agencies, and academic institutions to advance thermal-hydraulic understanding and practical applications.
The mission aligns with strategic objectives set by Commissariat à l'énergie atomique et aux énergies alternatives, collaborating with agencies such as International Atomic Energy Agency, Nuclear Energy Agency, European Commission, Agence nationale de la recherche, and national regulators like Autorité de sûreté nucléaire. It contributes to policy and standards through partnerships with Organisation for Economic Co-operation and Development, World Association of Nuclear Operators, Electric Power Research Institute, and International Organization for Standardization. The unit supports international consortia including Generation IV International Forum and European Atomic Energy Community, while interfacing with research infrastructures such as Cadarache, Saclay, and Grenoble laboratories.
The organizational chart reflects divisions for experiments, computation, and safety analysis, with leadership linked to Commissariat à l'énergie atomique et aux énergies alternatives headquarters and coordination offices in Paris and Grenoble. Facilities include large-scale loops, test rigs, and hot cells colocated with Cadarache and experimental halls near Institut Laue–Langevin and European Synchrotron Radiation Facility. Support units collaborate with Université Paris-Saclay, École Polytechnique, MINES ParisTech, CEA LIST, and industrial partners such as EDF, Framatome, Orano, and Siemens Energy.
Research themes cover single- and two-phase flow, boiling crisis, pressurized thermal shock, and severe accident phenomenology, aligning with work by OECD/NEA, IAEA, Generation IV International Forum, and consortia like International Collaborative Project on Fuel Safety. Methodologies integrate experimental campaigns influenced by programs at Argonne National Laboratory, Los Alamos National Laboratory, Sandia National Laboratories, and Brookhaven National Laboratory, with theoretical foundations referencing contributions from André Blondel and concepts used at Harvard University, Massachusetts Institute of Technology, Imperial College London, and ETH Zurich.
Computational tool development involves coupling system codes and CFD: examples include approaches comparable to RELAP5, TRACE, OpenFOAM, ANSYS Fluent, and research implementations akin to NEPTUNE_CFD. Numerical methods draw on work from Stanford University, Princeton University, University of Michigan, and Delft University of Technology. Experimental techniques use diagnostics similar to those at Paul Scherrer Institute, CERN, Oak Ridge National Laboratory, and JAERI, employing high-speed imaging, laser Doppler velocimetry, particle image velocimetry, wire-mesh sensors, and X-ray radiography adapted from ESRF instrumentation.
Applications emphasize accident management, emergency core cooling, and containment thermal hydraulics, integrating regulatory criteria established by Nuclear Energy Agency, International Atomic Energy Agency, and national bodies like UK Civil Nuclear Authority and US Nuclear Regulatory Commission. Studies inform reactor designs such as Pressurized Water Reactor, Boiling Water Reactor, Supercritical Water Reactor, and Generation IV concepts promoted by Generation IV International Forum members. Work supports operators and vendors including EDF, Framatome, Areva (historical), Westinghouse Electric Company, and research programs at Kurchatov Institute and Toshiba.
Collaborative projects span bilateral and multilateral frameworks with OECD/NEA working groups, European Commission-funded projects, and research networks like SNETP, EERA, CIDER-style consortia, and programs with Argonne National Laboratory, Idaho National Laboratory, CEA, CNRS, INRIA, CEA LIST, CNES, and universities including University of Cambridge, University of Oxford, Technical University of Munich, and KTH Royal Institute of Technology. Participation includes benchmarks and experiments coordinated with OECD/NEA committees and interlaboratory comparisons involving Paul Scherrer Institute, JAEA, KAERI, KIT, and CEA partner labs.
Training activities connect to higher education programs at Université Paris-Saclay, École Polytechnique, MINES ParisTech, Sorbonne University, and international graduate schools at Massachusetts Institute of Technology, ETH Zurich, Imperial College London, and Delft University of Technology. Technology transfer engages industrial partners EDF, Framatome, Orano, Siemens Energy, and standards bodies such as ISO and AFNOR. Outreach includes doctoral supervision, postdoctoral exchanges with Argonne National Laboratory, Oak Ridge National Laboratory, and secondments to industry affiliates like Westinghouse Electric Company and Toshiba.
