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.”

Smooth and uniform solid D-T layers inside a spherical shell are needed to achieve ignition on the Laser Megajoule (LMJ) facility. The thermal environment around the capsule is the key to reach the low-mode D-T layer requirements. During the nineteenth Target Fabrication Meeting in Orlando, Florida (2010), an analytical model was presented to predict the low-mode time evolution of a D-T layer in a capsule caused by a thermal perturbation. The model showed that the dynamical response is ruled by the redistribution time constant. To check the validity of the model, experiments have been done with deuterium layers inside an integrating sphere. The use of an infrared laser to generate a volumetric heating of the deuterium allowed us to tune the conformation time constant. The experimental setup has also been modified to allow or cancel 300-K infrared radiation entering the integrating sphere, producing a local warming on the capsule. Using shadowgraphy techniques, we have been able to follow the dynamical behavior of the deuterium layer. Analyses conclude that the analytical model is right and can be used with confidence.
