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.

A track-etch method of neutron radiography using a new 10B4C converter was studied. Various characteristics of the track-etch films were measured and compared with a conventional emulsion method. The etch pit production rates, resolution powers, and graininess relating to the etching conditions were precisely investigated. Various fine radiographs were obtained, including simulated fast breeder reactor fuel and irradiated fuel pins. The resolution power and the image quality of the track-etch radiography were comparable to those using a combination of gadolinium foil and fine grain films with shorter exposure times.
