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 tokamak systems code (SuperCode) is used to identify lower-cost ITER options. Superconducting coil, lower-cost options are found by: (1) reducing the ITER technical objectives (e.g., driven burn and lower wall load), (2) using more aggressive physics (advanced physics) assumptions (e.g., higher shaping, better confinement, higher beta, etc.), and (3) more aggressive engineering assumptions (reduced shield/gaps and inductive requirements). Under ITER nominal physics assumptions, but designing for a driven Q = 10 operation results in ∼30% cost reduction if the required neutron wall load is dropped to 0.5 MW/m2. Assuming advanced physics guidelines leads to cost savings of up to 40% in an ignited device with a major radius as low as R = 5.5 m. Designing this device for Q = 10 results in additional cost savings of 10%. If reduced inboard shield and scrapeoff is assumed, and no inductive capability is required, machine size and cost benefits tend to saturate at about R = 5 m and 50% of the ITER-EDA cost.
