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?

A major challenge in nuclear fusion research is the coherent combination of measurements from heterogeneous diagnostics. Different measurement techniques for measuring the same subset of physical parameters provide complementary and redundant data for, e.g., improving the reliability of physical parameters, increasing the spatial and temporal resolution of profiles, and resolving data inconsistencies.The concept of integrated data analysis within the framework of Bayesian probability theory was applied to the combined analysis of lithium beam emission spectroscopy (LIB), deuterium cyanide laser interferometry, electron cyclotron emission (ECE), and Thomson scattering spectroscopy. The four heterogeneous diagnostics enable the simultaneous estimation of electron density and temperature profiles with high spatial and temporal resolution. The coherent analysis of the profile diagnostics allows one to consider diagnostic interdependencies correlating density and temperature profiles, e.g., ECE shine-through, and diagnostics alignment. The benefits of a combined analysis of diagnostics will be shown in a modular way by successively increasing the set of diagnostics starting with the LIB diagnostics.
