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.

A symmetry-based criterion is developed for arranging source locations to produce a nearly spherically uniform, volumetric deformation of a spherical target. The criterion requires that the source coordinates be combined in a certain manner to form an isotropic second-rank tensor. This criterion, combined with a method for maximizing the symmetry, produces a sequence of preferred configurations given by4T, 6C, 121, 201, 301, 321, 421, 501, 601, and 621,where the integer is the number of sources and where T, C, and I refer, respectively, to specific tetrahedral, cubic, and icosahedral symmetry arrangements. The results are of interest for a generic class of problems involving the excitation of a spherical medium through mechanical, thermal, or electromagnetic energy deposition by discrete sources.
