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.

Current compatibility research in the U.S. focuses on two topics: dual- or multi-layer electrically-resistant Y2O3/vanadium coatings in a V-Li blanket concept and SiC composites with a Pb-Li coolant. The compatibility issue for multi-layer coatings includes the ceramic insulating layer and the metallic vanadium alloy layer. Characterization of Y2O3 coatings after exposure to Li shows significant changes in the microstructure. Initial static capsule results for V-4Cr-4Ti alloys in Li at 800°C showed unexpected small mass gains. Capsule tests of monolithic SiC in Pb-17Li showed no mass change and no wetting after 1000h at 800°C and only limited wetting after 1000h at 1100°C. Chemical analysis of the Pb-Li after the tests did not detect Si to the detectability limit of 30ppma (5wppm). In both liquid metal systems, loop tests with a representative temperature gradient are needed to truly determine compatibility limits.
