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.”

In a high-yield, low repetition rate Inertial Fusion Energy (IFE) system, such as the Z-Pinch IFE reactor, compressible liquid/gas jets offer the opportunity to protect the cavity walls from the target X-rays, ions and neutrons. They can especially limit and mitigate the mechanical consequences of the shock waves produced by rapid heating/evaporation of the protective jets. In this investigation, experiments have been conducted to examine the stability of two-phase jets and quantify the extent by which they can attenuate a shock wave. An exploding wire was used to generate a shock wave at the center of downward flowing annular single- and two-phase jets within a concentric cylindrical enclosure. The pressure history at the enclosure wall was recorded as the shock wave propagated through the attenuating two-phase medium. Experiments were conducted using two different-size jets and enclosures at various liquid velocities, void fractions, and initial shock strength. The data showed that stable coherent jets could be established and steadily maintained with relatively high void fractions and that significant attenuation in shock strength could be attained at relatively modest void fractions. The data obtained in this investigation can be used to validate predictions of shock attenuation models for future IFE reactor cavities.
