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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

The TerraPower-developed mechanical analysis code OXBOW is used to evaluate the mechanical performance of Traveling Wave Reactor core assemblies. Benchmarking work was performed using OXBOW to compare displacement and contact load results against a variety of mechanical analysis codes from the International Working Group on Fast Reactors (IWGFR) for a set of well-defined assembly conditions. Significant differences in results were found in the benchmark problem modeling a thermally bowing row of assemblies in a limited free bow core restraint configuration. This is due to a bridging effect which occurs due to differences in contact modeling methodology. Additionally, significant displacement differences in results were found in the benchmark problem modeling duct dilation under internal pressure, temperature, and irradiation. These differences are due to the fact that OXBOW dilation models account for both stress relaxation and geometric nonlinearities. Differences in results between OXBOW and the IWGFR benchmark participants are attributed to higher fidelity models generated using OXBOW.
