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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Understanding and improving modeling of aerosol evolution in nuclear reactor accidents are important in estimations of the nuclear source term. We explore here the nature of some approximations inherent in the widely used sectional technique for both single- and multicomponent aerosols and the influence these have on results. We also describe our efforts toward improving the fidelity of the sectional technique to the actual physics by coupling the sectional technique with the direct simulation Monte Carlo simulations, and why such coupling has proved difficult.
