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 high heat flux ion beam test facility at Forschungszentrum Jülich can produce peak power densities of 0.14 to 12 kW/cm2 for pulse lengths of 10 ms to 15 s. Longer pulses up to steady-state operation are possible with reduced power. The total ion beam power can be varied between 70 kW and 6 MW at particle energies of 10 to 60 keV. The particles are hydrogen and helium. The beam illuminates a 1300-cm2 area, which allows a large area for materials tests. The rise time of the beam pulses can be adjusted between 2 and 200 ms, and the pulse repetition rate is between 1 and 5 min. The test facility is equipped with a sample manipulator with a vacuum lock that allows a sample size of 15 × 10 cm with active or passive cooling. The extensive diagnostic system of the test stand, originally designed for developing and conditioning the neutral beam ion sources for the Tokamak Experiment for Technology Oriented Research (TEXTOR), and the diagnostic system of the sample manipulator are described. The results of a materials test series performed for the development of wall materials for the Next European Torus/International Thermonuclear Experimental Reactor (NET/ITER) are shown. Possible upgrades of the facility are also discussed.
