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
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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.

More than 14 000 U-10Zr fuel rods (alloys of U with 10 wt% Zr) were irradiated in the Experimental Breeder Reactor II and Fast Flux Test Facility, with some irradiated to burnups of almost 20 at. %. However, very little information about properties of unirradiated U-10Zr alloys is available. These data are needed to help with interpretation of data from irradiated materials, to develop and validate phase diagrams and models of U-Zr and more complex systems, to inform and validate fuel performance codes, to design fuels for future fast reactors, and to guide future experimental investigations to fill in crucial gaps in knowledge.
This paper provides a summary and critical review of the available experimental data on phases and phase diagrams, electrical properties, thermal expansion, thermal conductivity, heat capacity, mechanical properties, vapor pressures, and thermodynamic properties of unirradiated U-10Zr alloys. Many of the reported values were published before approximately 1970 and are available only in obscure reports. This critical review concludes by identifying areas where additional experimental measurements are particularly necessary and makes recommendations on prioritization of new measurements with a view to the emerging needs associated with the mechanistic modeling of nuclear fuels and their performance.
