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
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

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.

Two-dimensional edge plasma turbulence as measured by high-speed H imaging is investigated in the TJ-II stellarator. An image analysis method based on two-dimensional continuous wavelet transformation is introduced. This method detects localized coherent structures (blobs) in the images and extracts their geometrical characteristics (position, scale, orientation angle, and aspect ratio). This paper studies the impact of edge shear layers (both spontaneous and biased induced) on these geometrical aspects of blobs. Results show a reduction in the angular dispersion of k ~ 1.2 to 1.4 cm-1 blobs as the shear layer (both spontaneous and biased induced) is established in the boundary, as well as a shift of the aspect ratio histogram toward higher values. The turbulence suppression induced by the biasing seems to be scale selective, more effectively suppressing k ~ 1.4 cm-1, ~ 4.5 cm structures than k ~ 0.7 cm-1, ~ 9.0 cm ones.
