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.”

Transport properties of tritiated water vapor (HTO) in the epoxy paint such as adsorption, desorption, diffusion and dissolution has been evaluated by investigating the HTO exposure and removal behavior from the epoxy paint in order to generate a data base on tritium behavior in tritium-confinement facilities such as the Hot Cell and the tritium plant building in ITER. Two types of experiments were carried out; one was the HTO exposure to the epoxy paint, and the other was the detritiation curves from the epoxy paint after the HTO exposure. Stainless steel vessel chambers with the epoxy painted inside surfaces were first exposed to an air flow containing HTO vapor (740 Bq/cm3) for 1 week, 2 weeks and 2 months. After these exposures, detritiation of these chambers with an air flow was carried out. It was found that the interaction between the surface of the epoxy paint and the HTO such as adsorption and desorption is reached the steady state under these conditions. Based on experimental detritiation curves, the transport properties were evaluated using the tritium transport analysis code, TMAP. The trapping effect is the strong bonds between the HTO and the epoxy such as the chemical bonds, which is represented by trapped HTO in this analysis. Although diffusivity and solubility of HTO in epoxy paints almost agreed with the previous investigations, trapping like effect should be considered to explain observed detritiation behavior.
