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.

Standard on fixed neutron absorbers in nuclear facilities outside reactors just issued (ANS-8.21)
ANSI/ANS-8.21-2023, Use of Fixed Neutron Absorbers in Nuclear Facilities Outside Reactors, has just been issued by the American Nuclear Society Standards Committee. The standard was approved by the American National Standards Institute (ANSI) on June 20, 2023, as a revision and consolidation of ANS-8.21-1995 (R2019) (withdrawn) (same title) and ANS-8.5-1996 (R2022) (withdrawn), Use of Borosilicate-Glass Raschig Rings as a Neutron Absorber in Solutions of Fissile Material. ANSI/ANS-8.21-2023 provides guidance for the use of neutron absorbers, including Raschig rings, as an integral part of nuclear facilities equipment, fissile material, or fuel components outside reactors, where such absorbers are credited to provide criticality safety control.
ANS STEM Academy Educator Series
January 26, 2023|5:00–6:00PM (6:00–7:00PM EST)
Available to All Users
The American Nuclear Society STEM Academy presented this free webinar on the nuclear fuel cycle developed specifically for K-12 educators. Mary Lou Dunzik-Gougar, a professor at Idaho State University and former ANS president, explained the nuclear fuel cycle, current technologies for spent fuel handling, and emerging technologies that reimagine nuclear waste management.
About Mary Lou Dunzik-Gougar
Dunzik-Gougar is the associate dean of the Idaho State University (ISU) College of Science and Engineering, associate professor of nuclear engineering and a senior reactor operator at ISU’s Aerojet-General Nucleonics nuclear reactor, commonly known as the AGN-201. Presently, she coordinates the nuclear engineering curriculum at ISU and teaches core graduate and undergraduate courses. Dunzik-Gougar also performs nuclear materials research and is involved in regional and discipline accreditations, ISU’s international program development, and reactor administration.
