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.

A new outer divertor is being designed for installation on Alcator C-Mod. This divertor will be toroidally continuous such that the currents during a disruption will be driven in the toroidal direction and not cross Alcator's large toroidal field and it eliminates leading edges. However, currents will still cross the poloidal fields, and so it is important to properly predict the poloidal fields in the area of the divertor so that we can properly predict the loads on the divertor during a disruption. To that end, an ANSYS model has been built which can predict the fields and field transients in C-Mod given two inputs, the currents for the toroidal and poloidal field coils which come from measured data taken during a discharge, and the current in the plasma, which comes from another model that solves Maxwell's equations to reconstruct the plasma as 24 current carrying filaments. The advantage of using this method to predict fields is that it provides the ability to create a model based on actual measured data and to model whichever type of disruption, whether a midplane disruption or a vertical displacement event, is deemed necessary for the design. The ANSYS model then is able to predict the fields, including the shielding effects of the structures in the vessel, and the currents induced in the vessel and these structures. These results can then be mapped to a sub-model of the divertor to predict loading and stress during the disruption.
