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.

The design of steam generator components operating in the creep range often involves sophisticated methods of analysis requiring a variety of test data. Creep, relaxation, stress rupture, and fatigue data are required, and in many cases it is necessary to extrapolate the data to the long-term service conditions. The 9% Cr—1% Mo steel in the normalized and tempered condition has a relatively high proof strength and good creep rupture strength and ductility properties; furthermore, its fatigue strength is little affected by creep. The % Cr—1% Mo steel is not so strong, and its creep-fatigue properties have not yet been sufficiently well defined to provide reliable design guidance in this area. Alloy 800 has a good rupture strength, and although design guidance for creep fatigue is available, recent results suggest that the values may need to be reviewed.
