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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

An efficient and simple method to compute one-dimensional steady-state and transient turbulent single-phase flows across singularities (e.g., sudden contractions or expansions in ducted flows) is presented. This method accounts for the effective inertia of a fluid at a constriction and the irreversible pressure losses caused by recirculation zones generated near a singularity. For selected singularities of technical interest, algebraic expressions for the equivalent inertia lengths and the hydraulic resistance coefficients are presented. The implementation of the method into one-, two-, and three-dimensional numerical fluid dynamics codes is explained and the limitations of the method are discussed. The method is also extended to two-phase flow where additional flow parameters characterizing the momentum exchange between the phases play a role.
