ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

U.S. reactor technologies to be featured at IAEA conference
A virtual side event at the 64th General Conference of the International Atomic Energy Agency will spotlight U.S. reactor technologies. The free event, US Reactor Technologies: Flexible Energy Security for Real-World Challenges, will be held this Thursday, September 24, from 9:00 a.m. to 10:30 a.m. (EDT).
The event will highlight the capabilities of small modular reactors and other innovative reactors for addressing countries’ current needs. It will also examine anticipated challenges in the future, as well as underscore the need to act now.
The event is sponsored by the U.S. Department of Energy’s Office of Nuclear Energy. Advanced registration is required.

This paper presents further investigation of the liquid phase catalytic exchange (LPCE) process on the LPCE-3 column (50-mm inner diameter and 2-m height) of the EVIO pilot plant. The characteristics of the column filled with alternating layers of RCTU-3SM hydrophobic catalyst and stainless steel spiral-prismatic packing have been studied at a catalyst/packing volume ratio of 2:1 and compared to a ratio of 4:1. The EVIO-5 computer model is used for the column performance evaluation (as before) but this time the mass transfer coefficient for phase exchange Bx is not fixed. Due to the unequivocal separation of the catalytic and phase exchange with the help of the EVIO-5 code, the comparison of catalyst activity given by mass transfer coefficient Kc has been made for the experiments at two different catalyst/packing volume ratios. The column performance has also been expressed by the value of the height-equivalent-to-theoretical-plate average along the column. Some experience concerning the control of an LPCE column operating at the mode “with independent flows” is discussed.
