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.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

Interaction between shear flows and plasma instabilities in axially symmetric mirrors can lead to improved confinement, observed both in experiments on the gas dynamic trap and in simulations. Shear flows, driven via biased end plates and limiters, in combination with finite-larmor-radius effects are shown to be efficient in confining high-beta plasmas even with a magnetic hill on axis. Interpretation of observed effects such as vortex confinement, i.e., confinement of the plasma core in the dead-flow zone of the driven vortex, is shown to agree well with simulations. Theoretical scaling laws predict such a confinement scheme to be useful even in fusion plasmas.
