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.

Lightbridge announces first U-Zr fuel rod samples extruded at INL
Lightbridge Corporation announced today that it has reached “a critical milestone” in the development of its extruded solid fuel technology. Coupon samples using an alloy of zirconium and depleted uranium—not the high-assay low-enriched uranium (HALEU) that Lightbridge plans to use to manufacture its fuel for the commercial market—were extruded at Idaho National Laboratory’s Materials and Fuels Complex.

Measurements of tritium concentration on the surface and in depth of various samples of constructional materials employed in nuclear power engineering have been made by making use of a magnetic microscope and a magnetic imager. -radiation images of large (up to 0.5 m) radioactive contaminated surfaces in a nonuniform magnetic field were obtained. The magnetic field uniformly increasing in the direction from the observable surface to the recording screen was used. The principal conditions of identical transfer of the image and its reduction coefficient were determined depending on the ratio of the magnetic fields on the sample surface and the screen. The experiments were carried out in vacuum conditions. The magnetic field was produced with a cylindrical rod of a magnetic material and in the screen area it was 0.5 T. Formation, transport and detection of images were fulfilled in a wide range of their reduction ratio (1-1/40).
