Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

Previous studies have explored the determinants of the nuclear proliferation levels (Explore, Pursue, and Acquire). However, these studies have weaknesses, including endogeneity and multicollinearity among the independent variables. This resulted in tentative predictions of a country’s nuclear program capabilities. The objective of this study is to develop a tool to predict future nuclear proliferation in a country, and thus facilitate its prevention. Specifically, we examine how applying deep learning algorithms can enhance nuclear proliferation risk prediction. We collected important determinants from the literature that were found to be significant in explaining nuclear proliferation. These determinants include economics, domestic and international security and threats, nuclear fuel cycle capacity, and tacit knowledge development in a country. We used multilayer perceptrons in the classification model. The results suggest that detecting a country’s proliferation behavior using deep learning algorithms may be less tentative and more viable than other existing methods. This study provides a policy tool to identify a country’s nuclear proliferation risk pattern. This information is important for developing efforts/strategies to hamper a potential proliferating country’s attempt toward developing a nuclear weapons program.
