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.

Low-frequency turbulence and the resultant cross-field plasma transport in mirror-based systems are studied by means of direct computer simulations of nonlinear plasma dynamics. Under the low-beta assumption the nonlinear dynamics are simulated in a frame of adiabatically reduced one-fluid MHD model. Simulations of self-consistent plasma evolutions have shown formation of large-scale flute-like stochastic vortex structures, which have broad-band frequency and wave-number spectra and are similar to the intermittent vortex-like structures observed in GAMMA 10 experiments. Simulations were performed both for the conventional tandem mirror configuration and for axisymmetric non-paraxial configuration with divertor-like separatrix. Various regimes of plasma confinement with sheared plasma rotation have been modeled and analyzed.
