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.

A new electrorefiner with a ceramic partition has been developed for pyrometallurgical reprocessing of metallic fuel. In this electrorefiner, dissolution of spent fuel and deposition take place simultaneously, resulting in an increase of the processing rate. The feasibility of this electrorefiner was confirmed by a polarization profile and a current efficiency of an electrotransportation of uranium from a pure uranium anode to an iron cathode through a liquid cadmium pool. Separation of active fission products from actinide was confirmed by a transportation of simulating fission product elements with and without imposing electropotential. The maximum cathode current density onto a liquid cadmium pool without formation of a dendrite was measured against the concentration, and it was found to decrease with increasing concentration of uranium in cadmium. The estimated time required to process 50 kg of heavy metal by the new electrorefiner was less than that of the original electrorefiner.
