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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Cascade performance is examined when the degree of enrichment per separative unit is arbitrary, but not small. An approach is developed that is applicable to new technologies, which project significant enrichment per unit. Analysis shows that ideal operation and minimum separative work do not occur concurrently and that neither is a reliable guide for optimizing costs for a small cascade. Cascade performance is studied in a systematic manner that keeps the feed assay, the product assay, and the amount of product fixed. Many small cascade configurations are examined, and the results are combined with a hypothetical operating curve, thereby generating a simplified relative cost evaluation. Three costs are considered: feed, mechanical pump power, and laser power. No single configuration optimizes all three, but the analysis does indicate the superiority of a few of the examined configurations.
