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.

Candidates for leadership provide statements: ANS Board of Directors
With the annual ANS election right around the corner, American Nuclear Society members will be going to the polls to vote for a vice president/president-elect, treasurer, and members-at-large for the Board of Directors. In January, Nuclear News published statements from candidates for vice president/president-elect and treasurer. This month, we are featuring statements from each nominee for the Board of Directors.

Deposition of tungsten-rhenium alloys by the simultaneous hydrogen reduction of tungsten and rhenium hexafluorides has been studied over the temperature range 450 to 700°C using a total system pressure of 10 torr and a H2/(WF6 + ReF6) ratio of about 20. Deposits formed on the inner wall of heated copper deposition tubes through which the reacting gases passed. Under these conditions the greater ease of reduction of ReFe6 compared to WF6 resulted in nonuniform deposits having a higher rhenium content near the inlet to the reaction zone than farther downstream. Deposits containing up to 46 wt% Re have been prepared. The use of argon with the reacting gases was found to improve homogeneity. The deposits were found to contain total interstitial impurities as low as 50 parts/106. The grain structure was typically columnar. X-ray diffraction revealed the presence of two phases that coexisted throughout part of the composition range: an alpha-tungsten (bcc) structure, which was the principal phase in low rhenium deposits, and a previously unreported beta-tungsten phase, which was favored by high rhenium contents.
