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.

Corrosion and creep behavior of tubes fabricated of three German stainless steels have been studied in a 10 000-h test in a sodium loop at 873 and 973 K. The measured weight losses depend on the temperature and the oxygen content of the sodium. The results of metallographic examinations with respect to the formation of ferritic surface layers are in agreement with element concentration profiles obtained by analytical techniques. The stabilized stainless steels pick up carbon from the sodium even at 973 K although the carbon content of the liquid metal is in the range of 0.1 to 0.2 ppm. The measured carburization corresponds to the thermochemical data of both the steels and the liquid alkali metal. The creep rates of two of the steels are not influenced by the sodium, and the third material in the cold-worked condition shows an acceleration of the creep by a factor of 5. The different behavior cannot be explained by structural or chemical changes in the materials due to the action of sodium. Future examinations will clarify the different effects of sodium on the behavior of the slightly different materials.
