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.

BREAKING NEWS: Trump issues executive orders to overhaul nuclear industry
The Trump administration issued four executive orders today aimed at boosting domestic nuclear deployment ahead of significant growth in projected energy demand in the coming decades.
During a live signing in the Oval Office, President Donald Trump called nuclear “a hot industry,” adding, “It’s a brilliant industry. [But] you’ve got to do it right. It’s become very safe and environmental.”

The dynamic behavior of aerosols is of considerable interest in nuclear reactor source term studies. Because of the intractable nature of the dynamics, this behavior is studied through solutions of a spatially homogenized equation. There has been a need, however, to understand the effect of the homogenization process on the calculated aerosol distributions. To provide insight into the nature of the approximation and the accuracy of the results calculated with the homogenized (averaged) equations, some typical aerosol distribution problems are solved both with the spatially dependent and the homogenized versions of the aerosol dynamic equations. Comparisons of results show that while in some instances homogenization can be quite useful, there are realistic circumstances where it can lead to substantial deviations from accurate results as obtained by the equation that allows for spatial dependence of aerosol distribution.
