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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

The heat load due to plasma radiation is estimated for the plasma wall components of the stellarator Wendelstein 7-X (W7-X). A fully three-dimensional Monte Carlo code is used to simulate heating of first-wall components due to photon emission from the plasma. The plasma wall components can be described in a complex way with arbitrary shapes and orientation and flexible numerical representation. The volume radiation distribution is assumed to be described by poloidal symmetric and radially varying one-dimensional profiles aligned to the magnetic flux surfaces. A further example is given by a nonpoloidal symmetric radiation distribution following the five X point regions of the island divertor magnetic structure. Several realistic and artificial radiation profiles are chosen to investigate the local heat loads on an idealized plasma wall. The first detailed technical application of the code is the estimation of the local heat load on the Thomson scattering windows and on the inner surface of several vacuum ports of one half-module of the W7-X plasma vessel.
