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.

In order to extensively and simultaneously analyze frequencies of fluctuations of the end-loss ion current, we prepared three types of analog-to-digital converters (ADC) whose sampling frequencies are 62.5 kHz, 333 kHz and 64 MHz, respectively. The low and intermediate frequency ADCs have 20 channels. The high frequency ADC has a single channel and analyzes the summed signal of the MCP detector. We observed the fluctuations of Alfvén ion cyclotron (AIC) mode and the beat phenomenon appeared in the end-loss ion current. On the energy distribution functions of the end-loss ion, we have already observed the gentle humps. We found the relation between the gentle humps and the AIC waves observed in the end-loss ion current, and confirmed by the pitch angle analysis of the beat fluctuation that the AIC waves significantly influenced the trapped ion to transport into the loss region.
