Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

Reaction rates of 115In(n, n′) and 90Zr(n,2n) were measured on various axial positions inside single slabs of 18-cm-thick beryllium and 15-cm-thick lead kept in front of a Haefely deuterium-tritium neutron generator. These experimental axial activity profiles, and those for the zirconium/indium ratio, are compared to those computed using the two-dimensional discrete ordinates code DOT 3.5 coupled to a compatible first-collision source evaluator code GREATUNCL. Generally, a satisfactory agreement is seen between these profiles for both beryllium and lead slabs.
