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.

Sellafield waste vault yields 1960s-era finds
A 1960s Electrolux vacuum cleaner was among the more unusual items workers removed from one of the world’s oldest nuclear waste stores at the United Kingdom’s Sellafield nuclear site.

Just recently, the ARIES team completed the detailed design of ARIES-ACT-1 with aggressive physics and advanced SiC technology. The ability of the SiC/LiPb blanket to provide tritium self-sufficiency was among the important issues investigated in detail. To pinpoint the design elements that degrade the breeding the most, we developed a novel stepwise approach that involves building the CAD model from scratch, and, in multiple steps, adding the internals/externals of the blanket. At each step, the impact on the tritium breeding ratio (TBR) was recorded to identify the more damaging/enhancing conditions or changes to the tritium breeding. The TBR approaches 1.8 for an ideal system, and then degrades to 1.05 for the ARIES-ACT-1 reference design. This paper sheds light on several breeding-related issues that puzzled the fusion community for decades and gives insight about the impact on TBR of the individual blanket internals as well as other essential parts of the tokamak.
