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.

The instantaneous effects of nuclear radiation on thermocouple calibration were measured using Chromel-Alumel and iron-Constantan thermocouples. Electromotive force shifts of 2 to 4°C were found at radiation levels of 1016 n/(cm2 sec) (fast and thermal) and 1010 R/h. These changes were attributed to local gamma heating of the thermocouple bead rather than to a change in the thermoelectric power of the thermocouple materials. In separate experiments, no transient changes were noted in thermocouple calibration (± 1.0°C) following a change in radiation level of ≤ 7 × 1012 n/(cm2 sec) (thermal and fast) and 7 × 106 R/h.
