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.

Natalie Cannon is passionate about nuclear policy
Some people are born leaders, and some people make themselves leaders. Take Natalie Cannon, a fourth-year doctoral candidate in the Department of Nuclear and Radiological Engineering and Medical Physics at the Georgia Institute of Technology. She has been driven to succeed since she was a teenager in Southern California, when she was inspired by NASA’s Mars Exploration Program.

In this study, we conduct a two-dimensional numerical analysis of double-diffusive natural convection in an emplacement drift for a nuclear waste repository. In-drift heat and moisture transport is driven by combined thermal- and compositional-induced buoyancy forces. Numerical results demonstrate buoyancy-driven convective flow patterns and configurations during both repository heatup and cooldown phases. It is also shown that boundary conditions, particularly on the drip-shield surface, have a strong impact on in-drift convective flow and transport.
