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.

In the fast ignition scheme, the compressed core is surrounded by a 1-mm-scale coronal plasma. The critical density where the laser deposits energy is still more than 100 m away from the core. The distance is much longer than the laser focus radius or the core size. This situation raises an important question: How can we couple laser energy to the core from such a distance? One of the techniques that has been proposed to overcome this problem is hole boring by the ponderomotive pressure of the incident laser light. In this paper, the physics related to the laser hole boring, including the parametric instabilities, the channel formation, and the hot electron acceleration by ultraintense laser light, are discussed. The maximum density where the laser can propagate by hole boring is obtained as a function of the intensity. This agrees well with experimental observations, and it is confirmed by numerical simulations. The acceleration mechanism of hot electrons in the magnetic channel is also identified. The hot electrons are characterized by the numerical simulations. In summary, the critical issue of energy coupling in this scheme is raised and discussed.
