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.”

As a part of the ARIES-CS compact stellarator power plant study, a modular, helium-cooled, T-tube divertor design that can accommodate a peak heat load of 10 MW/m2 has been proposed. Detailed analyses have been performed using the FLUENT[registered] CFD software package to evaluate the thermal performance at the nominal design and operating conditions. Extremely high heat transfer coefficients (>40 kW/(m2-K)) have been predicted. An experimental investigation has been undertaken to validate the results of the numerical simulations. A test module which closely simulates the geometry of the proposed He-cooled T-tube divertor has been tested using air as the coolant while maintaining the same non-dimensional parameter ranges as the He-cooled T-tube divertor design. Axial and azimuthal variations of the local heat transfer coefficient have been measured over a wide range of operating conditions. The experimental data closely match the model predictions. The results of this investigation show that the model can be used with confidence in future design analyses of the T-tube divertor, as well as similar types of gas-cooled high heat flux components.
