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.

President's Profile Steven Arndt: Prioritizing participation and advocacy
Steven Arndt began his one-year term last month as president of the American Nuclear Society, bringing the same high level of energy, investment, and action he has exhibited throughout his career. Reflecting on a life spent improving nuclear safety and technology, he notes that it’s not just the work; it’s also about the people and building connections and relationships. Arndt fondly recalls Peter Lyons, former NRC commissioner, assistant secretary of energy for nuclear energy, and ANS board member who passed away in April 2021. “I have been incredibly lucky to know and work with some great people in our field, and almost to a person they have been like Pete Lyons,” Arndt said. “They have been gregarious, outgoing, and supportive.”
