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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

The Compact Torus Accelerator (CTA), under development at Lawrence Livermore National Laboratory, offers the promise of a low-cost, high-efficiency, high-energy, high-power-density driver for ICF and MICF (Magnetically Insulated ICF) type fusion systems. A CTA with 100 MJ driver capacitor bank energy is predicted to deliver ~30 MJ CT kinetic energy to a 1 cm2 target in several nanoseconds for a power density of ~1016 watts/cm2. The estimated cost of delivered energy is ~3$/Joule. We discuss indirect-drive ICF with a DT fusion energy gain Q = 70 for a total yield of 2 GJ. A reactor system for CT injection, target emplacement, containment, energy recovery, and breeding will be described. The CTA naturally lends itself as a driver for MICF where an energetic (≈100 MJ) CT is injected into a containment sphere generating shock heating which initiates a magnetically insulated DT burn with refueling for Q ≃ 70 and a fusion yield of 7 GJ. The containment sphere, which is chosen to be several 14 MeV neutron mfp's thick, is vaporized and heated by fusion neutrons and expands into the main reactor containment chamber to form the working gas for direct electrical energy recovery through an MHD generator cycle. Application of the MICF system to spaceship propulsion will also be discussed.
