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.”

The interactions of gaseous molecular iodine with painted surfaces aged in French nuclear pressurized water reactors (PWRs) were carried out in an experimental facility consisting of a molecular iodine generator, a mixing chamber, a sampling chamber, a specimen holder, and a gamma-counting probe [Cristal NaI(Tl)]. The same experimental facility was used to precisely measure the gaseous molecular iodine interactions with epoxy-painted coupons conditioned by two artificial hydrothermal treatments, either by heating at 130°C in a dry atmosphere or by heating at 130°C in a saturated water atmosphere. Then, a kinetic model was developed to represent these experimental results.This paper examines if the previous kinetic model can be used to interpret the gaseous molecular iodine interactions with aged paints. With the rate constant values found for the artificially conditioned paints, the kinetic model agrees with experimental results. Moreover, for the three studied temperatures (95, 110, and 125°C), the values of initial adsorbed water concentration onto the paint and the adsorbed water concentration in equilibrium with the steam of the carrier gas are intermediate between the values found for the two artificial hydrothermal treatments.Finally, a kinetic model is available, allowing the evaluation of precise assessments of the gaseous molecular iodine interactions with aged epoxy paints in the case of a severe PWR accident.
