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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Optimal step assays and interstage up-flow rates for enriching and stripping sections of uranium gaseous diffusion squared-off cascades are manageably determined without any additional approximations beyond the usual ones (i.e., a close separation process and a constant cut in the whole section). This is accomplished by the application of the optimization conditions to the function to be minimized, i.e., the total up-flow rate, still expressed in integral form. The use of suitable dimensionless variables allows quick evaluations of the optimal parameters of any plant, provided that the product and waste assays range from 1 to 99% and from 0.05 to 0.65%, respectively, and that the number of enriching and stripping steps be, at most, seven and four, respectively. The results are consistent with those available in the literature; in particular, it is confirmed that, for low and intermediate product assays, a number of enriching steps higher than five is unnecessary in most cases.
