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.

Tokamak equilibria with a snowflake divertor configuration are studied using a wire current model in toroidal geometry. A set of conditions for the formation of a snowflake divertor that can also be applied in full equilibrium calculations using a Grad-Shafranov solver is presented. It is shown that by taking into account the vertical force balance of the plasma, previously obtained results using a simple wire model have to be corrected. For a reactor-type device with coils far away from the plasma to accommodate the shielding requirements, the poloidal field coil currents become so high that they will represent a major technological challenge.
