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.

The numerical analysis is performed with two dimensional wave code for controlling the eigenmode formation of fast Alfvén waves in the GAMMA 10 central cell. The plasma production by fast waves depends on the wave excitation in the plasma. Eigenmodes are strongly formed when the boundary conditions in the axial and radial directions are satisfied. As the optimum density for the formation of eigenmode exists discretely, the density is clamped at the value where the eigenmode is strongly formed. For the higher density plasma production, the eigenmodes must be continuously excited as the density increases. It is found that the almost continuous excitation of eigenmodes can be realized by using two waves with different frequencies at the same time.
