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
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.”

Global MHD stability calculations using the PEST code have been carried out as part of the US ITER team's High Aspect Ratio Design (HARD) study. Approximately 15,000 cases have been evaluated both for global and local (ballooning) modes. In addition to aspect ratio variations [2.78 < A < 5], a range of shapes (1.4 < κ < 2.0, 0. < δ < 0.6) has been examined and the safety factor has been varied: q(0) was varied from 1.05 to 1.85 and qψ from 3.1 to 4.55. For global aspect ratio scaling, these results show no significant increase or decrease in the maximum Troyon parameter, within the level of variation imposed by profile differences: the scaling of the maximum Troyon parameter (g) is found to be independent of A, if optimal values are considered at each aspect ratio. Specific results for the HARD configuration (A = 4.0, κ = 2.0, δ = 0.4 and q = 3.1, 4) show that the grequired can be obtained with values of 1i(3) = 0.65 – 0.85 in both the ignition and steady state phases.
