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?

The analysis of Faraday rotation measurements shows that the safety factor on the magnetic axis stays well below one during the full sawtooth cycle.The current density profile has a unique shape during the sawtoothing plateau phase of ohmic discharges, independent of plasma current and magnetic field, when it is plotted in suitable normalized coordinates.The observation of short lasting spikes on the Faraday rotation signals can be interpreted as the formation of a transient current sheet during the sawtooth crash.Direct measurements of the magnetic amplitude of the internal kink mode with a fast polarimeter channel show that the displacement of the core because of the growing precursor mode stays much smaller than the q = 1 radius just prior to the sawtooth collapse.The versatile neutral beam heating system on Tokamak EXperiment for Technology Oriented Research (TEXTOR) allows the study of the influence of the plasma rotation on the sawtooth period, which has a minimum when the magnetohydrodynamic rotation in the tokamak frame is stopped.
