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.

Nuclear new build procurement considerations
It may seem counterintuitive, but the best time to enhance the ability to support operations and maintenance for a new plant is before construction starts. This is one of many lessons learned by the currently operating nuclear fleet. As construction and startup of many nuclear facilities was completed, it quickly became evident that the ability to efficiently support operations and maintenance was limited. Most of the information necessary to establish and manage procurement of spare and replacement items, maintenance, and configuration of the facilities was unavailable and had to be gathered on a case-by-case, “on-demand” basis. Absence of necessary information and the associated challenges resulted in the need for staff augmentation and multiyear-long projects to develop equipment bills of material and maintenance programs and to perform technical evaluations for the huge quantities of spare and replacement items being requested.

Noncontact radiography is developed to determine the doping concentration of inertial confinement fusion shells based on an improved equivalent absorption method by real-time X-ray imaging. Elements of high atomic number (high-Z)/middle atomic number (mid-Z) are doped into the shells to prevent hot electrons from preheating the fuel and to restrain the growth of hydromechanic instability. In this paper, an improved equivalent absorption model is developed to determine doping concentration by real-time X-ray imaging. Compared to contact radiography (CR) with film imaging, this technique can be used to obtain doping concentrations at different angles as a supplement to the CR method, even if the dynamic range of a charge-coupled device is less than film imaging. Experiments are carried out to determine the doping concentrations of Ge-doped and Si-doped shells. Uncertainties of the results are analyzed, and the expanded uncertainties are approximated to 0.1 at. % (K = 2, confidence factor). The experimental results show that there is a high level of agreement between this method and energy dispersive spectroscopy with the modified model.
