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.

The choice of the mandrel material has a significant bearing on the properties of the sputter-coated beryllium shell needed for NIF targets. Here, we present our work on screening four mandrel materials, their impact on the Be shell and issues related to their subsequent removal. Beryllium shells sputter deposited on hollow glow discharge polymer or GDP spheres met most of the target specifications. However, they had greater opacity due to partial oxidation of the Be during the GDP burnout step. Poly (-methyl styrene), silicon and nickel beads were explored as alternative mandrels but were plagued with problems such as cracking of the Be shell or incomplete removal. The most promising approach was a two-step coating process mediated by a thin 6m Be mandrel that is made using GDP.
