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.

In the new Replacement Tritium Facility (RTF) at the Savannah River Site, gloveboxes and stripper systems are used to minimize tritium release to the environment. The RTF was built to handle kilogram levels of tritium. It was started up and has been in operation since January 1994. The glovebox-stripper system has performed well in confining tritium leaks from the process. The tritium level in the gloveboxes has been maintained at below 0.1 Ci/m3 under normal conditions. During a large leak of tritium gas from the process to a glovebox, the tritium concentration in the glovebox shot up to about 4000 Ci/m3. However, there was no significant release of tritium to the environment. The tritium reading in the glovebox decreased to a 10 Ci/m3 level after 6 days of stripping. The performance of the glovebox-stripper system during this tritium leak and the possible factors for the long and slow decay of the tritium concentration in the glovebox are discussed in this paper.
