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.

Steam is a sign of cooling system function . . . at ITER
Steam from one of ITER’s ten induced-draft cooling cells offers visual confirmation of a successful cooling system test, the ITER organization announced April 30. ITER’s cooling system features 60 kilometers of piping with pumps, filters, and heat exchangers that can pull water through at up to 14 cubic meters per second. Once fully operational, two cooling loops—one to remove the heat generated by the plasma in the ITER tokamak and one for its supporting infrastructure—will be capable of extracting up to 1,200 MW of heat.

The magnet system of the full sized ITER (Final Design Report (FDR) version), has progressed to the point where basic sizing has been accomplished and local details are being addressed. The ITER US Home Team has worked on global structural models of the magnet system as well as local models of components that are strongly coupled with the global behavior. Areas of interest include the crown – monorail -slot interaction, proposed outerintercoil structure (OIS) cover plates, and case wall thickness studies. The root of the crown slot is highly stressed. Specialized fabrication techniques will be needed to eliminate flaws from this area to meet fatigue criteria. The fluted geometry of the outer cylinder was not found to contribute to the Out-of-Plane (OOP) support of the The inner leg. TF case thickness was studied and it was concluded that the sidewalls of the case may be thinned up to 7cm in selected regions between the OIS. A cover added to the outside of the middle OIS was found to improve the shear loads at the flange pins. The use of 20 vs. 10 support structures for PF 1 and 9, is recommended.
