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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?
Uranium Chemistry Tutorial
February 2, 2021|10:30AM–12:00PM (11:30AM–1:00PM EST)
Available to 2020 ANS Virtual Winter Meeting Attendees
ANS Members, please log in to watch this webinar.
This is part nine of a nine-part tutorial series exclusively available to 2020 ANS Winter Meeting attendees.
Understanding the physical constraints and behaviors imposed on a uranium system by chemistry is helpful in establishing necessary criticality safety controls for the process. For single batch operations or for processes that involve only a few chemical reactions that occur effectively instantly, end state chemistry is often sufficient for analysis. However, processes like separations involved multiple stages of continuously occurring chemical reactions and mass transfer that evolve over time. In these cases, predictive chemistry simulation can be a powerful tool in understanding the behavior of the system and imposing appropriate criticality safety controls. The presentation will include an overview of separations methods and equipment, introduction to the mathematics of simulating mass transfer, an overview of available computations programs and their capabilities, and an example process analysis of an industrial scale high enriched uranium purification system.
