ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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 Stein Industrie steam generator of the 250-MW(e) demonstration fast breeder reactor Phenix comprises three units. Each unit is divided into 12 evaporator modules, 12 superheater modules, and 12 reheater modules. Twenty-four evaporators are made of 2¼ Cr—1 Mo ferritic steel and 12 are made of 2¼ Cr—1 Mo—1 Nb stabilized ferritic steel. All superheaters and reheaters are made of 321 austenitic steel. Since Oct. 1973, this steam generator has been submitted to a number of startups and shutdowns and some 9000 h of operation at full load without any leak, with an acceptable hydrogen diffusion rate of 0.25 g/h per unit through the single wall of the tubes. The Fives-Cail Babcock steam generator selected for the 1200-MW(e) Fast Breeder Power Plant Super Phenix is comprised of four modules with a 357-tube helical bundle made of Alloy 800 housed in a shell made of an austenitic steel (Type 304 or 316L). The module is rated at 750 MW(th) and weighs 140 tons. Other steam generators made of ferritic steels are considered in the longer range for power plants beyond Super Phenix.
