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.

The compatibility of tungsten, W-0.9wt%Cb, W-10wt%Re, W-25wt%Re, TZM (Mo-0.5wt%Ti-0.08 wt%Zr), Mo-50wt%Re, and rhenium in static lithium was determined. Exposures were at 2500, 2800, and 3000°F for periods of 100 and 1000 h. Exposures were conducted in TZM containers for all alloys tested. The results obtained must be viewed in light of the dissimilar capsule employed. The tungsten-base materials were not attacked by lithium after 100- or 1000-h exposure at 2500°F. At 2800°F, all of the tungsten-base materials exhibited varying degrees of surface dissolution and grain-boundary penetration. TZM and Mo-50wt%Re alloys were resistant to attack by lithium at up to 3000°F for 100- and 1000-h exposure. Unalloyed rhenium underwent dissimilar metal interaction while immersed in lithium in TZM test capsules for 1000 h at 2500°F and 100 h at 3000°F. Molybdenum was transferred from the TZM corrosion capsule to the rhenium where alloying occurred.
