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.

A preliminary conceptual design study for a very low activation fusion plasma core experimental facility is presented. Low activation is achieved by using only very low activation materials in the inner shield (graphite blocks), vacuum vessel (Al/SiC composite alloy), outer shield (SiC/B4C) and magnets (Aluminum). The mechanical configuration of the vacuum vessel is a water-flooded double-shell. It is capable of carrying 1.5 MN in hoop compression with a reserve factor of two over the equatorial 0.8 m zone during plasma disruption. Hands-on access to the vacuum vessel and auxiliary equipment provide a high degree of operability, maintainability and flexibility in experimental program. Problem areas are in further development of the aluminum alloy and composite materials for the vacuum vessel and in cost reduction of high purity low activation materials.
