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.

Pacific Fusion predicts “1,000-fold leap” in performance, net facility gain by 2030
Inertial fusion energy (IFE) developer Pacific Fusion, based in Fremont, Calif., announced this morning that it is on target to achieve net facility gain—more fusion energy out than all energy stored in the system—with a demonstration system by 2030, and backs the claim with a technical paper published yesterday on arXiv: “Affordable, manageable, practical, and scalable (AMPS) high-yield and high-gain inertial fusion.”
The American Nuclear Society (ANS) Standards Board shall be responsible for policy and procedural direction for the standards activities of the Society. The Standards Board oversees the activities of the Standards Committee. The Standards Committee is a historical term that is used to identify professionals who participate in various committees allocated by the Standards Board. The Standards Committee does not conduct itself as a committee. It does not meet nor act as a single body. It is simply a collection of qualified volunteers who participate in the development and maintenance of ANS consensus standards and related documents.
The Standards Committee is responsible for the development and maintenance of standards that address the design, analysis, and operation of components, systems, and facilities related to the application of nuclear science and technology. The scope includes the development and maintenance of standards on the following subjects and closely related activities:
The Standards Committee does not develop standards for the application of radiation for medical purposes. The Standards Committee may review standards being developed or issued by other organizations on related topics to help ensure consistency and completeness and to avoid duplication. Standards developed by the Standards Committee are intended to be issued as American National Standards.
