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
Nuclear Energy Conference & Expo (NECX)
September 8–11, 2025
Atlanta, GA|Atlanta Marriott Marquis
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.

Uranium powder can readily be prepared by hydriding solid uranium and by the decomposition of the hydride. The powder particles are of –325 mesh size. This powder compacts to density varying between 12 and 14 gm/cc. Sintering subsequent to compacting results in a material of high strength characterized by a slight porosity and coarse grain structure. Hot pressing uranium powder in the alpha temperature range at pressures of approximately 10 to 15 tsi results in a material of perfect density and a small grain structure. Hot compacting uranium powder is a process perfectly feasible for production.
