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.

Institut fur Plasmaphysik, Kernforschungsanlage Julich GmbH, Association EURATOM-KFA, Julich, West Germany The variation in the steady state hydrogen permeation flux magnitude through composite metals under both molecular and atomic hydrogen upstream driving conditions is discussed. With molecular hydrogen upstream, the permeant flux magnitude does not depend on the permeant direction through the composite. Under atomic hydrogen bombardment conditions on the upstream side, however, this magnitude does depend on the permeant direction. In a two layer system, the permeant flux magnitude is enhanced by orienting the composite metal such that the layer with the higher product of solubility (S) with surface recombination rate constant (kr) faces downstream. Furthermore, the degree of asymmetry in the hydrogen flow (forward permeation/reverse permeation) increases with decreasing upstream pressure. First measurements on a copper-clad mild steel membrane are presented and confirm the expected permeation performance.
