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 effects of H2O contamination on lattices of natural uranium metal in D2O were measured in the exponential facility of the Savannah River Laboratory. The buckling changes associated with H2O contamination were determined for two lattices with moderator-to-fuel volume ratios of 12.3 and 14.6 over a range of H2O concentrations from 0.2 to 8.2 mol %. The agreement between calculated and experimental changes in buckling for these lattices was within ±25 × 10−6 cm−2. Similar measurements on seven other lattices with moderator-to-fuel ratios in the range from 31 to 212 were made for a change in the H2O concentration from 0.18 to 3.92 mol %. For these measurements the experimental change in buckling was about 15% greater than the calculated change.
