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.

The 2025 ANS election results are in!
Spring marks the passing of the torch for American Nuclear Society leadership. During this election cycle, ANS members voted for the newest vice president/president-elect, treasurer, and six board of director positions (four U.S., one non-U.S., one student). New professional division leadership was also decided on in this election, which opened February 25 and closed April 15. About 21 percent of eligible members of the Society voted—a similar turnout to last year.

This paper presents the capabilities of the International Database on Reactor Pressure Vessel (RPV) Materials (the Database) for precise and comprehensive RPV lifetime assessment, aimed at supporting the long-term operation of nuclear power plants. The Database was created in the framework of the International Atomic Energy Agency activities. Fourteen countries, including the United States, France, and Russia, supplied large amounts of surveillance results and data from national and international research programs.The recent achievements and open issues in the area of RPV radiation embrittlement assessment are considered. They concern mainly the effects resulting from long irradiation times and high neutron fluences (neutron flux influence, late blooming phases), nickel and manganese synergism, and further validation of appropriate safety concepts (the Master Curve approach).New information from ongoing surveillance and research programs has to be incorporated into the Database for the most effective RPV radiation embrittlement prediction. These additional data will greatly support the development of embrittlement correlations and embrittlement trend curves valid for long irradiation times.
