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.

DOE extends Centrus’s HALEU production contract by one year
Centrus Energy has announced that it has secured a contract extension from the Department of Energy to continue—for one year—its ongoing high-assay low-enriched uranium (HALEU) production at the American Centrifuge Plant in Piketon, Ohio, at an annual rate of 900 kilograms of HALEU UF6. According to Centrus, the extension is valued at about $110 million through June 30, 2026.

The time-dependent and steady-state solutions for the transmission of a gaseous radioactive isotope through an adsorber bed are derived. The transmission, defined as the ratio of the outlet concentration to the inlet concentration, depends on three dimensionless quantities, namely, the dispersion number Δ, the product of the radioactive decay constant and the propagation time λtp, and the dimensionless time t/tp. Based on the mathematical results, criteria are given for the design of adsorber beds for decreasing the concentration of a radioactive contaminant. An example illustrates the possibility of reducing the radioactivity of short-lived xenon isotopes in a carrier gas flowing through adsorber beds; however, consideration must be given to the low efficiency of the adsorber bed resulting from dispersion effects.
