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 mixed W-Be layers were prepared by deposition of Be and W atoms on a Be substrate under simultaneous sputtering of Be and W targets by 20 keV Ar+-ions. The thickness of the deposited mixed W-Be layer was ∼500 nm. The element composition analysis of these layers showed that the mixed layer contains up to 35 at.% W, up to 35 at.% Be and up to 30 at.% O. The W-Be films on Be were irradiated by pulsed deuterium plasma flux in the electrodynamic plasma MKT-accelerator with a deuterium plasma concentration of 1021 m−3, maximal ion energy of (1–2) keV and with the energy flux density of 0.2 MJ/m2 per pulse. The pulse duration was equal to 60 μs. After irradiation by two plasma pulses the W-Be film is melted and removed completely from the local surface areas. The element distributions in a mixed layer after an effect of the pulsed plasma are essentially changed. For the surface areas with the removed film the Be concentration is about 75 at.%, W — about 15 at.%, O - about 10 at.% and the penetration of W and O atoms is up to 1000 nm deep of Be substrate. For the surface areas with the retained melted film the Be surface concentration increase up to 90 at.%, tungsten and oxygen concentration decrease about 2–3 times. The method of Elastic Recoil Detection Analysis was used to study D retention. The integral deuterium concentrations are equal to 0.6·1020 and 2.2·1020 m−2 for the removed film areas and for the retained melted film ones, correspondingly. Consequently, deposited W-Be film promotes the essential reduction of D retention in Be substrate. Transmission electron microscopy was used to study the erosion product size distribution. The erosion products were collected on basalt filter fibers located in a shadow of the pulsed plasma flux around the exposed WBe film target. The erosion product size distribution has two maxima located in the ranges 0.1–0.2 μm and 2.5–5.0 μm.
