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.

To cover a large number of possible high-temperature reactor applications in the Federal Republic of Germany, the fuel element is designed to be uniform and acceptable for conditions set by different approaches for various plants following the thorium high-temperature reactor (THTR). To minimize fission product release, silicon carbide coated fuel (Triso) is required for all types of fuel cycles, and limits are specified for both fabrication and in-service coating defects. Fabrication processes using precise classification of coated and overcoated particles by tabling techniques ensure satisfaction of specified limits on fabrication-induced coating defects. A comprehensive irradiation test program was performed for both high-enriched uranium/thorium fuel elements used in the THTR and Arbeitsgemeinschaft Versuchs-Reaktor cycle and the low-enriched uranium fuel elements to be used for follow-up projects. The results demonstrate good performance of all types of fuel.
