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.

As an important part of the ITER gas injection system, the fusion power shutdown system delivers large quantities of gas into the vacuum vessel to stop the fusion power in an emergency case. Two identical but independent units are designed for mutual redundancy. Each unit includes an injection pipeline and a unit that contains a gas reservoir, solenoid valve, pneumatic isolation valve, and pressure switches. Among these components, the working gas reservoir parameters are investigated by experiments based on the required total gas quantity of at least 3000 Pa m3 neon or mixtures of neon and hydrogen injected within 3 s. The working gas is released utilizing a pneumatically actuated valve that is not affected by the strong stray magnetic field of about 0.205 T. The associated solenoid valve is equipped with magnetic shielding that is designed by a magnetostatic analysis. These components lie on the same plane in the unit to maximize the maintainability. Furthermore, the structure integrity of the unit and its support frame is validated by a preliminary structural analysis.
