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.

In the gas dynamic trap experiment with 17 keV and 4.5 MW deuterium neutral beam injection the spatial profile of fast ion density has been studied by different methods: MSE spectroscopy, active charge-exchange diagnostic and measurement of DD fusion product fluxes. The characteristic radius of fast ion density profile was found to be about 7 cm at 1/e level mapped onto the GDT midplane, that is close to gyroradius of 10 keV deuteron and less than the estimated region occupied by the captured ions(~15 cm). The analysis of energy balance shows that discrepancy between measured and simulated values (~1.5 times) cannot be explained by enhanced fast ions loses. Simplified theory of fast ion density spatial profiles formation shows that energetically profitable configuration has narrow radial profile. Physical mechanisms of density profile formation are also described.
