ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

UWC 2020: A call for transformational change
Bowing to current COVID-19 realities but buoyed by the success of June’s virtual Annual Meeting, ANS event planners returned to the virtual realm for this year’s Utility Working Conference. Originally scheduled for August 9–12 at Marco Island, Fla., the condensed event was held Wednesday, August 11, wherever registrants’ computer devices happened to be located.
In addition to 26 educational sessions and workshops, UWC 2020 featured an opening plenary session titled “Achieving Transformational Change: A leadership discussion,” moderated by Bob Coward, MPR Associates principal officer and ANS past president (2017–2018). Plenary panelists included representatives from three utilities—Arizona Public Service (APS), Exelon, and Xcel Energy—plus the Institute of Nuclear Power Operations (INPO) and the Nuclear Regulatory Commission.

To produce the laser targets needed for laser plasma experiments, the CEA target department uses different mechanical machining techniques and develops methods that are consistent with the target requirements in terms of quality, timing, and cost.
Combining these aims involves several challenges. First, laser experiments need a wide range of target geometries with common points: reduced dimensions (millimetric range) and thin walls (micrometric range), as well as very strict dimensional and geometric specifications. According to these requirements, the target specifications demand the machining of different kinds of materials from metals (aluminum, copper, and gold) to polymers and low-density foams.
In this context, the versatility of the machining processes is the key issue. These challenges necessitate the development and upgrading of machining techniques and methods as well as optimizing the engineering design to use the full potential of these techniques. In this presentation, three main machining processes are developed and illustrated: adaptations of machine tools for planar targets (by the flycutting method) and for machining complex shapes (combined milling and turning), the development of the original process to produce a baffle hohlraum, and the parametric optimizations of machining tantalum aerogel.
