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
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

General Kenneth Nichols and the Manhattan Project
Nichols
The Oak Ridger has published the latest in a series of articles about General Kenneth D. Nichols, the Manhattan Project, and the 1954 Atomic Energy Act. The series has been produced by Nichols’ grandniece Barbara Rogers Scollin and Oak Ridge (Tenn.) city historian David Ray Smith. Gen. Nichols (1907–2000) was the district engineer for the Manhattan Engineer District during the Manhattan Project.
As Smith and Scollin explain, Nichols “had supervision of the research and development connected with, and the design, construction, and operation of, all plants required to produce plutonium-239 and uranium-235, including the construction of the towns of Oak Ridge, Tennessee, and Richland, Washington. The responsibility of his position was massive as he oversaw a workforce of both military and civilian personnel of approximately 125,000; his Oak Ridge office became the center of the wartime atomic energy’s activities.”

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.
