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.

This study assesses the resource throughput and utilization of various thorium-based fuel concepts for near-term deployment in a pressure-tube heavy water reactor (PT-HWR). Such fuel concepts may be of interest to nations with thorium reserves that are interested in exploiting PT-HWRs. Given that nations with abundant thorium reserves and relatively small uranium reserves have an interest in reducing their dependence on natural uranium (NU) imports, the thorium-based fuel concepts are assessed in terms of their ability to conserve uranium resources and their impact on national income using an economic multiplier analysis. It is found that there are some thorium-augmented and thorium-based fuel concepts that are capable of both conserving resources and reducing reliance on importing NU, which would reduce the negative impact on national income from importing NU. A PT-HWR fuel bundle concept of 1.2 wt% 235U/U + Th (in a central fuel element and small amounts mixed into the outer 36 fuel elements) was found to be the most advantageous and attractive for implementation to improve nuclear fuel resource utilization.
