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.

The critical experiments reported provide data for the effect of a soluble neutron absorber (cadmium nitrate) on the criticality of high-enriched uranium nitrate solution. These data can be used in criticality control and for validation of calculational methods. The experiments were performed with cylindrical vessels of two different diameters, 241.8 and 291.6 mm. Cadmium concentrations used in the high-enriched uranium solution ranged up to ∼11 g Cd/ℓ. The vessels were reflected with water, and in some cases with water containing dissolved cadmium nitrate. The cadmium was found to be an effective neutron absorber when dissolved in the solution. The critical experiment data were analyzed by several different calculational methods, which showed the calculated keff values to increase as the cadmium concentration was increased. (The critical system calculated as supercritical.) The trend of the analysis results suggests that the neutron leakage or cadmium absorption may be underestimated for systems with a harder neutron spectrum.
