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?

Some open traps, like GOL-3, may be heated by axial electron beams. Since the heating is turbulent, it is associated with anomalous resistivity, so that the reverse induction current is pushed out to flow in the shell plasma along the beam edge. It is shown that such complicated distribution of axial current in equilibrium causes exponential amplification along the trap of any initial (at entrance) azimuthal modulation of the beam current density. As a result, the shape of the beam cross-section develops features like spiral arms, etc. at the end-plate, even if its shape was nearly circular at the entrance. Amplification occurs whenever there is an off-axis extremum on the radial distribution of the axial current density.
