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.

Current profile reproduction has been considered one of the key issues for control and evaluation of a tokamak plasma. Although magnetic measurements exterior to a plasma provide the most reliable data necessary for profile reproduction, the reproducibility from the magnetic measurements is unclear, and the regularization against numerical ill posedness improperly restricts reproducible profiles. To solve the inverse problem, at first, a new method is proposed for the current profile reproduction using a function expansion. Second, with the eigenfunctions in this method, a reproducibility check is analytically formulated. Finally, a new constraint for the plasma interior is derived from the MHD equilibrium equation. In the next step, this constraint must be included to enable reliable reproduction of current profile.
