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.

Uncertainty contributes to lowest uranium spot prices in 18 months
A combination of plentiful supply and uncertain demand resulted in spot pricing for uranium closing out March below $64 per pound, with dips down to about $63.50 during mid-March—the lowest futures prices in 18 months, according to tracking by analysis firm Trading Economics. Spot prices have also fallen steadily since the beginning of 2024. Meanwhile, long-term prices have held steady at about $80 per pound at the end of March, according to Canadian front-end uranium mining, milling, and conversion company Cameco.

In the design process of a cryogenic distillation plant for the separation of hydrogen isotopes, two main objectives, often impossible to achieve simultaneously, are taken into account: a high separation factor for different mixtures and isotope concentrations and the reduction of design, manufacturing, and operating costs with increased efficiency and safety. All this should result from the use of a method for calculating the separation efficiency, a method that will generate a conceptual design that must form the basis of the final technical design. Unfortunately, most design methods treat these plants as chemical plants, although in the case of cryogenic plants, it is not possible to readjust the new process operating parameters quickly and with great precision so that the separation efficiency and performance are not affected. There are three causes affecting the separation performance of cryogenic distillation plants, namely, nonideality of the cryogenic process, imperfection of heat exchangers, and heat losses. This paper presents our proposed solutions for increasing the efficiency of the cryogenic distillation process and discusses solutions tested in experimental campaigns with the cryogenic distillation stand developed in the Cryogenic Laboratory at ICSI Rm. Vâlcea.
