Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.

The DITE tokamak has a bundle divertor capable of operating in the maximum toroidal field of 2.7 T. A scanning infrared camera with a framing rate of 50 f.p.s. has been used to determine the power and power density at the divertor target. For discharges with 1.4 MW of neutral injection, peak diverted powers of nearly 400 kW were observed during the neutral injection period, representing 24% of the total input power. Power densities on the ion drift side of the target of up to 30 MW m−2 were measured for these discharges. Discharges without neutral injection show a maximum power diversion when the gas puffing is switched off.
