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.

Hot-pressed α-silicon carbide temperature monitors were irradiated at 525 and 772°C to 4.8 × 1021 n/cm2 (E > 0.18 MeV). Postirradiation isochronal annealing was carried out for 1-h periods at either 25 or 50°C intervals between 300°C and 1200 to 1500°C. Above the irradiation temperature the sample length decreased linearly with annealing temperature, while the electrical resistivity increased exponentially with temperature. Straight lines were fitted through the length-versus-temperature and log (resistivity)-versus-temperature data points and the temperature, T1 at which the line intersected the as-irradiated base line was measured. For both length change and resistivity, mean values of T1 agreed with the measured irradiation temperature within experimental accuracy. The precision of a single determination of T1 was obtained from curve-fitting statistics and was about ±20°C for irradiation at 525°C and ±30 at 772°C (90% confidence limits) for both length and resistivity measurements. The sample-to-sample reproducibility of T1 was estimated from the standard deviation of four repeated measurements and was similar to the precision of a single determination.
