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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

This paper introduces current issues, challenges, and future directions of nuclear thermal-hydraulic (T-H) safety research, viewed in close conjunction with new developments in advanced reactor systems and simulation tools and lessons learned from the Fukushima accident.
Two technical concerns are introduced to illustrate some of the limitations in our current understanding of important T-H phenomena that are very relevant to nuclear safety. The first is reflood heat transfer, which has been an important safety issue for a long time, and the second is the multidimensional T-H phenomena appearing in nuclear reactor systems, which have rather recently drawn significant attention in the nuclear community. These concerns are discussed by taking some recent research examples and emphasizing their critical relevance to nuclear reactor safety.
Then, some challenging issues for the advancement of nuclear T-H safety technologies are identified and briefly discussed in close conjunction with recent research efforts, and perspectives on advanced nuclear T-H safety research are presented.
