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.

Dragonfly, a Pu-fueled drone heading to Titan, gets key NASA approval
Curiosity landed on Mars sporting a radioisotope thermoelectric generator (RTG) in 2012, and a second NASA rover, Perseverance, landed in 2021. Both are still rolling across the red planet in the name of science. Another exploratory craft with a similar plutonium-238–fueled RTG but a very different mission—to fly between multiple test sites on Titan, Saturn’s largest moon—recently got one step closer to deployment.
On April 25, NASA and the Johns Hopkins University Applied Physics Laboratory (APL) announced that the Dragonfly mission to Saturn’s icy moon passed its critical design review. “Passing this mission milestone means that Dragonfly’s mission design, fabrication, integration, and test plans are all approved, and the mission can now turn its attention to the construction of the spacecraft itself,” according to NASA.

Experiments of H2-HT isotope separation were carried out with a hot wire column of 3 cm in diameter and 1.5 m in length. Separation factors were measured with cut changed from 0.1 to 0.9, and other operational conditions; pressure, feed rate and temperature difference, fixed. First, the feed rate was altered under the constant pressure, and next, pressure was changed. Experimental results were compared with those from an axisymmetric separative analysis, based on a Newton iterative solution of a convection-diffusion equation. Pressure dependence of separation factors agreeed qualitatively with those from theory. The separative power has a maximum value at 0.12 ∼ 0.16 MPa, when the feed rate was under 100 cm3/m(at 0.1 MPa, 25°C).
