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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.
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.

The hydrogen distribution in the oxidized Zircaloy-2 was related to its microsturcuture by tritium microautoradiography based on a cathodic tritium charging method. It was found out that hydrogen atoms were concentrated in the intermetallic precipitates such as Zr(Fe,Cr)2 and Zr2(Fe,Ni) existing in the oxide film, and on the grain boundary of zirconium matrix. It was also found out that hydrogen atoms were scarcely present in the thin metallic region adjacent to the oxide layer, the thickness of which was about 10–15 µm.
