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.

Solubility effects were measured on ceramic and single crystal alumina, titania, SrTiO3 (perovskite structure), and ceramic zirconia at 300 and 400°C for times of 7 and 18 days. Selected fluids were deionized water, a high-bicarbonate, high-sulfate simulated connate water (∼1% total dissolved solids), saturated NaCl brine, and a high-magnesium, high-calcium bittern brine. There is measurable dissolution of Al3+ in the connate water and in the bittern brine only. In both cases this can be related to the low pH conditions expected in these fluids at high temperature and to the increase in aluminum solubility with decreasing pH. The SrTiO3 breaks down to some extent in all fluids in the order bittern brine >NaCl >bicarbonate water >deionized water. Dissolution attack on both titanium and zirconium oxides is very small, indicating that the oxides are stable in the pressure-tempera-ture-fluid composition regime. Breakdown of the perovskite phase appears to be by incongruent dissolution with concurrent precipitation of the titanium oxide.
