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.

A new computational model for fusion power plant system studies is being developed for the ARIES program. An operational design space has been created to explore the most influential parameters in the physical, technological and economic trade space related to the developmental transition from experimental facilities to viable commercial power plants. This allows examination of a multi-dimensional trade space as opposed to traditional sensitivity analyses about a baseline design point. The influence of multifunctional, highly dependent parameters can easily be visualized, which may highlight one or a few difficult-to-achieve parameters that would yield a highly acceptable design solution. The new ARIES systems code consists of adaptable physics, engineering and costing modules which capture the current tokamak knowledge database and reflect both near-term as well as advanced technology solutions that are higher risk but have higher performance potential. To fully assess the impact of the range of physics and engineering implementations, the plant cost accounts have been revised to reflect a more functional cost structure. All of these features have been validated against the highly respected ARIES-AT baseline. The present results demonstrate novel visualization techniques for trade space assessment of attractive tokamaks for commercial use.
