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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Gigantic fusion-fission inertial confinement (I.C.) reactor systems can produce much power and very large quantities of nuclear materials such as T, He-3, U-233, Pu, etc. Before engineering such I.C. reactor systems, a much smaller, flexible all-fission I.C. test reactor system should be built. In this test reactor explosions of about 100 tons (420 gigajoules) are contained within a 30 meter diameter sturdy chamber and studies could be made of: containing inertial confinement explosions seriatum; using sodium slurries as the working liquid; processing slurry captured explosion debris; fabricating nuclear explosive assemblies; using Pu, Be, Li, and D for the production of T and He-3; breeding plutonium from depleted uranium; breeding uranium-233 from Th; etc.
