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.

Nuclear News 40 Under 40 discuss the future of nuclear
Seven members of the inaugural Nuclear News 40 Under 40 came together on March 4 to discuss the current state of nuclear energy and what the future might hold for science, industry, and the public in terms of nuclear development.
To hear more insights from this talented group of young professionals, watch the “40 Under 40 Roundtable: Perspectives from Nuclear’s Rising Stars” on the ANS website.

The upper, equatorial, and lower diagnostics port plugs in ITER will include numerous intermingling labyrinths and many streaming paths whose impact should be carefully studied. For this purpose, the 3-D Discrete Ordinates code, Attila, has been routinely used by PPPL/UCLA to assess the nuclear field in these geometrically complex plugs both during operation and after shutdown. In this paper we describe the calculation procedure followed and the input parameters/assumptions applied to assess the shutdown dose rates (SDDR) everywhere with emphasize on their values inside the generic equatorial port plug (GEPP) and its inter-space extension area. Factors inherent in the Discrete Ordinates method that impact the accuracy of the results (e.g. quadrature sets used, boundary conditions applied, etc.) are discussed. Means to minimize streaming through straight gaps and open channels present in the GEPP are presented in this paper, along with an examination of their effectiveness in reducing the SDDR in the port inter-space area.
