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.
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.

Control of the release of radioactive iodine is an important task of the air filtration system in a nuclear installation. The filtration efficiency of an active charcoal filter for methyl iodide is shown to decrease due to the poisoning of the filter by secondary materials in the gas stream. A model is developed that appears to reproduce the decrease in filtration efficiency. Lack of detailed information on the poison-filter interaction prevents definitive confirmation of the model The model facilitates the choice of the optimum values of certain micro-structural and operational parameters of the filter, to reduce the effect of secondary poisons on the filter and thereby to lengthen the usable life of the filter. The microstructural properties addressed by the model are catalyst pellet size, porosity, surface area per gram, and pore radius. The operational parameters of the filter are the gas transit time and the gas diffusivity in the catalyst pores as controlled by the gas temperature.
