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 the next generation of fusion device in China, e.g., the Experimental Advanced Superconducting Tokamak (EAST), the divertor target will be exposed to high heat loads up to 5 MW/m2 for about 1000 s. An actively water-cooled target plate element with flat tungsten tile armored on CuCrZr heat sink was designed for EAST. A two-dimensional finite element method (FEM) code was used to analyze its thermal and mechanical properties under high heat flux of 10 MW/m2 for the selection of an appropriate cross section. To meet the integrated requirements of temperature and stress in the target element, twisted tapes have to be inserted into the cooling channels to strengthen the heat transfer efficiency, and a tungsten armor thickness of 4 mm and a distance of 2 mm from the interface to the vertex of the cooling channel were ultimately selected. The thermal and mechanical properties of two kinds of tungsten armor (sintered and plasma sprayed) were also analyzed and discussed in the FEM calculations. The designed structure can be used under the 5 MW/m2 heat load expected for normal operation of EAST device, but it would suffer from cracks/failure danger under higher heat load, up to 10 MW/m2.
