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.

An outline of Next European Torus safety and its impact on the environment is presented. Included are a short characterization of the basic safety approach, current radiological recommendations, and the potential hazards due to tritium, neutron-induced radioactivity, and energy inventories. Significant accidents that could be initiated and propagated by these energies and finally lead to releases of radioactivity are characterized by typical initiating events such as after-heat under loss-of-cooling conditions and ruptures of blanket components. The environmental impact of releases is dealt with by reporting experimental results on tritium behavior in the environment as well as by broadly quantifying tritium dispersion and activation product releases under both routine and accidental conditions. Finally, the categories of wastes produced, their approximate amounts, and a strategy for their final disposal are presented.
