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 Fokker-Planck equation for the transport of energetic charged particles in hot plasmas and for one-dimensional plane geometries is solved by a new multigroup approach. The numerical scheme proposed here takes into account the strong anisotropy of the Coulomb scattering operator, as well as the possible large values of the removal cross section. Numerical results are given for two particular examples: the transport of protons in a boron hydride plasma and of 3.5-MeV alpha particles in a deuterium-tritium plasma. A good agreement is achieved with corresponding results from a less general “moment method” developed in previous works.
