  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.

  Supreme Court rules against Texas in interim storage case
  The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

India is a partner in ITER and plans to test its lead lithium ceramic blanket test blanket module. This component is embedded with a large number of cooling channels of different profiles and, therefore, is a challenging component to fabricate. Cooling channel reconstruction by employing high-power laser welding provides a promising scheme to fabricate this component. Cooling channel reconstruction was demonstrated in American Society for Testing and Materials A387 Gr91 steel using high-power CO₂ laser welding. A scheme for fabrication of scale models of different subcomponents, like the first wall (FW) and inner back plate, and assembly of the two subcomponents employing the cooling channel reconstruction scheme was demonstrated. The steady-state temperature field around the weld joint was computed using the welding and heat treatment simulation solution package SYSWELD. These weld joints were characterized for microstructure at different length scales, microhardness, and room-temperature tensile properties. This paper presents the scheme used for cooling channel reconstruction and the results of the weld joint characterization. The scheme for fabrication of the scale model of the FW, the inner back plate, and joining of the two subcomponents using the cooling channel reconstruction approach is also described in this paper.
