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
2021 Student Conference
April 8–10, 2021
North Carolina State University|Raleigh Marriott City Center
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.

A day in the life of the nuclear community
The November issue of Nuclear News is focused on the individuals who make up our nuclear community.
We invited a small group of those individuals to tell us about their day-to-day work in some of the many occupations and applications of nuclear science and technology, and they responded generously. They were ready to tell us about the part they play, together with colleagues and team members, in supplying clean energy, advancing technology, protecting safety and health, and exploring fundamental science.
In these pages, we see a community that can celebrate both those workdays that record progress moving at a steady pace and the exceptional days when a goal is reached, a briefing is delivered, a contract goes through, a discovery is made, or an unforeseen challenge is overcome.
The Nuclear News staff hopes that you enjoy meeting these members of our community—or maybe get reacquainted with friends—through their words and photos.

For hydrogen isotope enrichment/separation applicable to fusion fuel processing, environmental tritium safety confinement, or recovery of tritium from heavy water reactors, a hydrogen displacement adsorption process system is recommended using molecular sieve 5A as the separation material. For simulation and optimization of the process, mathematical models and a solving method are provided to calculate the breakthrough curves during the displacement adsorption, in which various parameters including pressure drop and mass transfer coefficients are allowed to be changeable. Based on the calculated results, the effects of the column size, the flow rate, and the outlet pressure on the enrichment factor, the recovery ratio and the separation ability of the column are comprehensively analyzed. The conclusions have some theoretical guiding significance for the development of hydrogen isotope separation by the displacement adsorption method.
