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.

The effects of producing a net toroidal current in the Fusion Engineering Device (FED-A) by using an input magnetosonic (or fast) wave to modify the alpha-particle velocity distribution function through momentum transfer via the transit time damping process are studied. The alpha-particle distribution becomes anisotropic, producing a net current through collisions with the background electrons. The fast wave is found to be accessible, and resonances at cyclotron harmonics and the ion-ion hybrid layer can be minimized by choosing ω ∼ 4ωCD, where ωCD is the deuterium cyclotron frequency. The calculation is based on an alpha-particle velocity distribution function accounting for slowing down against the background plasma electrons. The efficiency of the process is found to compare favorably with lower hybrid current drive, but the magnitude of the induced current falls short of the FED-A design current with the assumed value of the wave parallel magnetic field.
