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.

NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.
2024 ANS Student Conference
Dr. Lauren Garrison is a Senior Materials Scientist at Commonwealth Fusion Systems. She oversees materials development and testing projects for the ARC fusion power plant as well as solving near-term materials challenges for the SPARC experimental fusion device. Her areas of expertise include neutron irradiation of materials, refractory materials as plasma facing components, plasma-material interactions, and composite development. She previously spent 9 years at Oak Ridge National Laboratory during which time she was a Weinberg Fellow and group leader of the Advanced Nuclear Materials Group. Dr. Garrison holds a bachelor’s from the Nuclear, Plasma, and Radiological Department at the University of Illinois at Urbana-Champaign and a master’s and PhD from the Nuclear Engineering and Engineering Physics Department of the University of Wisconsin-Madison. She is the Chair of the Fusion Energy Division of the American Nuclear Society.
