ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

In water-cooled reactors measures to minimize the radiation fields due to the transport and deposition of 60Co are important to ensure low occupational doses of radiation. For example, it is now accepted practice to add zinc to boiling water reactor coolant to minimize 60Co transport and pickup by surfaces. This paper describes a study of the kinetics of 60Co deposition on Type 316 stainless steel in neutral, partially deoxygenated water at 563 K and 10.2 MPa with and without zinc traced with 65Zn. The effect of zinc addition on the corrosion rate of preoxidized stainless steel was also studied using relatively high concentrations of additive. General observations and a mathematical model of the corrosion rate provide insights into the possible mechanisms involved.
