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.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Vanadium alloys are planned for use as structural materials in fusion reactor blankets. To confirm the applicability of these alloys in fusion reactors hydrogen isotope mass transfer and inventory of vanadium alloys must be understood. In the present work, results obtained by performing experiments on hydrogen permeability through vanadium alloy VCr4Ti4 with different surface element compositions of the sample are presented and discussed. Changes of surface element composition were registered by means of Auger Electron Spectroscopy (AES). Experiments were carried out in the temperature range from 573 to 873 K, at input pressures of hydrogen from 102 to 103 Pa. The differential variant of steady state technique with the registration of gas quantity permeated through sample by means of mass-spectrometer was used in these experiments. Parameters of hydrogen permeation through the vanadium alloy at different surface element compositions of the sample were determined. Experiments have shown that the concentration of nonmetallic impurities sulfur/carbon on the surface has a strong influence on the hydrogen permeability through the vanadium alloy (VCr4Ti4).
