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 continuous release of fission gas from ceramic fuels is measured during irradiation in the Oak Ridge Research Reactor. The fuel specimens are heated by their own fission power which is controlled by moving the specimen holder into or out of the neutron flux. Fuel specimens with thin cross sections are used, both to prevent thermal stress rupture and to allow accurate temperature measurement. A continuously flowing sweep gas carries the fission gas outside the reactor where the radioactive isotopes are measured with a gamma-ray spectrometer. The specimen temperature is controlled by air cooling the specimen holder. The experiment is instrumented to function continuously and unattended.
