Division Spotlight
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

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.

Controlled fusion research and development would not have proceeded nearly so well and might have stagnated in the United States and elsewhere without the international collaboration experienced to date. It is noted that: (a) the time perspectives are long, and the prospects for fusion will remain unclear for one or two more decades; (b) the costs and uncertainties will be minimized, and the prospects for success maximized, by increased collaboration during that period, which will benefit all participants; (c) the time is not yet ripe for building a large international (several billion dollar) fusion feasibility experiment; and (d) the best mix will consist mainly of nationally supported, but mutually decided on, programs. Specific suggestions are given.
