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.

Reactivity effects associated with the mitigation of unprotected loss of flow in sodium fast reactors are being studied to find ways to reduce the potential release of mechanical energy.The studies performed with ERANOS illustrate the importance of cladding removal as well as radial leakage changes during the core slumpdown. Possible arrangements and dispositions are envisioned that would avoid recriticality and hence the possibility of going into severe power excursions.Challenges to be faced by safety studies that would ascertain that no cliff-edge effects occur are then listed.
