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 thermal and structural conceptual design and an analysis of tritium permeation are presented for the grid tubes and collector plate of the interim MARS tandem mirror reactor. Designs are presented for two thermal recovery concepts, a water coolant with low outlet temperature and gaseous coolant with high outlet temperature. System analyses were conducted for the grids. For the grids both radiative and actively cooled schemes were investigated. Three water cooled grid tube point designs were studied. For the liquid cooled collector, five coolant channel configurations were considered. A reference design was chosen for the grids and collecter plates.
