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.

Energy is everything

Energy is the foundation of modern society. It enhances quality of life and drives industrialization. As we work toward fuller energy transition, policies are essential to organizing our march forward. Bipartisan legislation is doing just that, propelling our current and future actions.
The Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act will help propel the work of industry, academia, and several branches of government in exciting—and necessary—directions.
The Senate introduced the act in March 2023, and the House of Representatives passed the Fire Grants and Safety Act, which incorporated the ADVANCE Act, on May 9, 2024 (393–13). Then on June 18, the Senate passed the ADVANCE Act (88–2), and on July 9, President Biden signed the bill into law. New and revised approaches to process and deployment of nuclear energy capacity is well on its way. Below, I have highlighted a few title sections to show scope and significance.

The objective of this work is to study the coolability limits of stationary porous structures and loose particle accumulations that might occur in liquid-metal fast breeder reactor subassemblies. Due to the simple geometry of the test sections, it was possible to produce a motion picture and coordinate it with the mass flow and temperature measurements. This approach has been shown to provide an adequate picture of the cooling mechanisms, especially at sodium boiling. A remarkable difference in boiling behavior in stationary porous structures and movable particle accumulations has been observed. Stationary porous structures are very sensitive to non-rewetting hot spot formation and dryout, whereas particle accumulations tend to form fluidized bed structures at sodium boiling. Dryout heat flux correlations for both the stationary porous structure and the movable particle accumulation have been developed from the experimental results.
