Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight
Nuclear Energy Conference & Expo (NECX)
September 8–11, 2025
Atlanta, GA|Atlanta Marriott Marquis
Standards Program
The Standards Committee is responsible for the development and maintenance of voluntary consensus standards that address the design, analysis, and operation of components, systems, and facilities related to the application of nuclear science and technology.

CEA/Valduc has developed a Thermal Cycling Absorption Process (TCAP) experimental device dedicated to the study of the separation of hydrogen isotopes and particularly to the recovery of tritium from low concentrated mixtures (tritium molar fraction < 6%). Simultaneously an original and efficient dynamic simulation tool has been developed in collaboration with PROSIM Company. After a brief description of the TCAP process device developed and the establishment of the modelling approach adopted, a deeper understanding of the complex TCAP behavior is lighted on through some simulation results. Then, a sensitivity analysis of the TCAP operating parameters on its global performance and particularly on the tritium contamination in the head flow is presented. Finally, all these results are applied to propose an optimized operating sequence for the recovery of tritium from low concentrated hydrogen mixtures.
