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.

Oak Ridge National Laboratory addresses compelling challenges in delivering carbon-free fusion and fission energy systems. The lab traces its roots to the X-10 Graphite Reactor, the world’s first continuously operated nuclear reactor, and to early innovations in fusion research and engineering.
ORNL has unique facilities for materials research and high performance computing that support our scientists and engineers in addressing challenges such as extended operations of the current US nuclear reactor fleet; investigating economical and flexible advanced reactor systems; and making fusion energy a viable power source.
ORNL also leads US ITER, which is responsible for designing, fabricating, and delivering hardware systems for the international ITER fusion project that will demonstrate 500 MW of fusion power. The directorate also leads the Transformational Challenge Reactor program, which leverages advanced manufacturing for rapid and economical deployment of nuclear technologies, and the Material Plasma Exposure eXperiment (MPEX), a future world-leading capability that will produce the extreme plasma environments to test materials for use in fusion energy devices.
