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.

Join us in person in beautiful New Orleans for the third installment of Materials in Nuclear Energy Systems, MiNES, to focus on research in the fission reactor materials community. The MiNES conference series grew out of two biannual symposia: Microstructure Processes in Irradiated Materials (MPIM), held at the TMS Annual Meeting & Exhibition, and Nuclear Fuel and Structural Materials (NFSM), held at the ANS Annual Meeting. The conference takes place biannually, with TMS and ANS alternating sponsorship.
