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.

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

Recent favorable results on START have caused renewed interest in low aspect ratio tokamaks. To design an economical next-step spherical tokamak to study confinement scaling and high beta plasmas, we have developed a transport scaling and device optimization code. This code OPT, benchmarked against START, includes 10 empirical confinement scaling laws and essential tokamak physics such as stability limits. Parameters are optimized separately for each scaling law and physics goal. Using OPT we find for R/a=1.2 to 2.0 one can achieve βN=5 and <β>=30% with just two neutral beams (PNB<3.5 MW) for Ip≥0.75 MA, and Ro≥0.6 m. In contrast, if one insists on using the nominal device parameters, Ip=1 MA and Ro=0.8 m, with each scaling law, achieving βN=5 requires typically PNB⋍7.5 MW.
