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.

Wyoming as a hub for new nuclear manufacturing and microreactor deployment?
A 60-year-old Wyoming industrial machinery company is partnering with nuclear innovator BWX Technologies to deploy 50-megawatt microreactors in America’s heartland over the coming years to provide carbon-free heat and power for industrial users.

A computationally efficient method for analyzing magnetohydrodynamic (MHD) flow is used to investigate flow in a channel with a high aspect ratio that is mechanically strengthened by the use of anchor links. The method used is the core flow approximation, which neglects inertial and viscous effects and the induced magnetic field. This reduces the governing equations to a set of linear equations. These assumptions are often valid at the high magnetic fields characteristic of a fusion reactor. The slotted duct shape is used to reduce the MHD pressure drop, which may be excessive in liquid-metal blankets. It may be necessary, however, to use anchor links in the design, and these anchor links introduce an additional pressure drop. The analysis shows that the size is more important than the conductivity of the anchor link. Depending on the size of the anchor link, the pressure drop is shown to increase by as much as 100% for the geometries analyzed.
