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.
Meeting Spotlight
International Conference on Mathematics and Computational Methods Applied to Nuclear Science and Engineering (M&C 2025)
April 27–30, 2025
Denver, CO|The Westin Denver Downtown
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.

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

A pulsed Nd:YAG laser is being used to aerosolize material from the surface of metal targets to simulate particles created in fusion energy systems. Targets in the form of rods up to 2-cm diameter can be attached to a screw mechanism that exposes a fresh surface for each laser pulse. Energies up to 20 J/pulse can be applied to the target, at pulse rates from a single shot to 300 Hz. Energy can be focused on an area with diameter less than 500 µm. Stainless steel and aluminum targets were used in a demonstration of system performance. The branched-chain ultrafine aggregate aerosols that were produced appeared to result from direct vaporization/condensation of material from the surface of the target located under the center of the laser beam, and from ejection of molten droplets from the target surface.
