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.

Texas-based WCS chosen to manage U.S.-generated mercury
A five-year, $17.8 million contract has been awarded to Waste Control Specialists for the long-term management and storage of elemental mercury, the Department of Energy’s Office of Environmental Management announced on November 21.

The hypervapotron (HV) has been demonstrated to be a superior thermal management (TM) and high heat flux removal (HHFR) technique for fusion reactor plasma-facing component applications involving a single-side absorbed heat flux (up to between 20 and 30 MW/m2). However, the conjugate heat transfer HV flow channel (HFC) only can be optimized completely when the related HHFR controlling parameters have been identified. In an earlier work, Part I of the present effort, we identified three high heat flux-side controlling TM and HHFR dimensionless parameters and a characteristic temperature difference. In the present work, six HV wall conjugate heat transfer dimensionless primary controlling parameters and five secondary controlling parameters have been identified. The controlling parameters include the effects of (1) most geometric specifications of the array of fins; (2) variations in the HV wall thermal conductivity and heat transfer coefficient; (3) effective Biot numbers characterizing effects that include the fin array, a typical fin example, and the side walls; (4) the HFC unobstructive portion flow aspect ratio, and (5) the HFC wall aspect ratio.
