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.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

The paper describes the electric field in stellarator equilibria and discusses the methods of how to compute the electric potential. The momentum balance in a given magnetic field including viscous and friction forces is considered in the frame of a multifluid model. A general ambipolar condition on closed pressure surfaces is derived that is still valid if magnetic surfaces do not exist. The need for an extended model originates from the singularities of the plasma current in the ideal magnetohydrodynamic model of stellarator equilibria, where parallel current density becomes singular leading to singular parallel electric fields. Viscosity and friction forces eliminate these singularities. The paper investigates the mathematical implications of the extended plasma model and discusses the existence of solutions using the methods of functional analysis.
