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.”

Ion cyclotron resonance heating is a reliable tool for high-power and long-pulse operation in fusion reactors. However, a sudden increase in the reflected radio-frequency (RF) power poses serious problems such as L- to H-mode transition or edge-localized modes that must be solved for future fusion reactors. It is necessary to place an impedance matching system between the RF generator and antenna to mitigate the adverse effects of the variations. The idea of a fast-response ferrite stub tuner was developed to trace the load variation of the antenna. This study presents theoretical calculation of the suitable normalized mechanical length of the ferrite stub tuner using transmission line theory and numerically analyzes the impedance matching parameters of the single ferrite stub antenna system. The present study demonstrates the feasible investigation of the magnetic field modulation, which can lead to the effective reduction in the reflected RF power fraction during the large change in plasma resistance.
