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.

Forschungszentrum Karlsruhe conducted and sponsored a study on containment loads from hydrogen combustion pressures that could occur in case of an unmitigated severe accident in a future 1500-MW(electric) pressurized water reactor. The analysis of large-scale distribution tests leads to the conclusion that the full spectrum of combustion modes from slow deflagration to global detonation must be considered in the absence of any hydrogen control system. New experimental and theoretical results are presented for fast flames, deflagration-to-detonation transitions, and marginal and stable detonations in hydrogen-air mixtures on reactor relevant scale. Maximum possible combustion loads for severe accidents are predicted for a typical dome geometry. The results provide a database on global combustion loads for design studies on future severe accident resistant containments.
