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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

We have tested typical polymeric materials related to the water detritiation system to evaluate their contamination by tritiated moisture and water. The polymeric samples were exposed to 740-1110 Bq/cm3-gas of tritiated moisture with a 1kPa of H2O pressure at a temperature ranged 288 to 298K for various times up to 70 weeks. The other polymeric samples were immersed directly in 70000 Bq/cm3-liquid of tritiated water at a temperature ranged 288 to 298K for various times up to 52 weeks. After the test samples were exposed, the concentrations of tritiated water absorbed in the sample were evaluated by static leaching method. The exposure time to HTO moisture affected negligibly the concentrations of HTO absorbed in the samples. The immersion time in liquid HTO in contrast affected strongly the concentrations of HTO absorbed in the samples, due to penetration of HTO. Appropriate polymeric materials were clarified in the light of HTO contamination.
