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
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

Nuclear in K-12 education: Overview of ANS toolkit and reflections from educators
A free webinar today from 3:00 p.m.-4:30 p.m. (EDT) will look at the resources that the American Nuclear Society has developed with Discovery Education and the Department of Energy’s Office of Nuclear Energy to help K-12 educators teach nuclear science and technology.
The webinar will begin with an overview of the resources, followed by reflections and commentary from three educators of various grade levels on their experiences teaching nuclear science and their thoughts about ANS’s instructional materials. The webinar will conclude with a Q&A session with the panelists.
Registration is required for this Nuclear Science Week event.

A technique to monitor the permeation behavior of tritium in metals to pure water was successfully developed. A metal membrane separated two containers: one is for tritium loading as an upstream side, and the other is for tritium permeation release as a downstream side. Tritium was loaded by gas absorption at controlled temperatures of 303 K, 323 K, and 373 K and pressures of 4 and 8 kPa at the upstream side. Pure water in the downstream side was automatically and continuously circulated to a solid scintillation counting apparatus by which the tritium concentration in the pure water was directly measured for more than 100 h. When the present technique was applied, almost diffusional permeation behavior of tritium at the nickel-water interface was demonstrated.
