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.

Tank waste operations resume at Idaho’s IWTU
The Department of Energy’s Office of Environmental Management announced yesterday that waste processing operations have resumed at the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory Site. The resumption of operations follows the completion of two maintenance campaigns at the radioactive liquid waste treatment facility.

High-purity V-4Cr-4Ti low activation alloy products, such as plates and wires, were fabricated from the NIFS-HEAT-1 ingot with improvements of the conventional manufacturing processes. During fabrication, significant and small increase in hydrogen and oxygen level were observed, respectively. However, these contaminants were released by a heat treatment at 673 K or higher in a vacuum. For the purpose of obtaining an appropriate thermomechanical treatment condition, recrystallization behavior of plate products, which were 6.6, 4.0, 1.9 mm thick, was investigated after cold rolling. It was revealed that annealing at 1273 K for one to two hours provides recrystallized grains of 20-30 μm. Only in the case of 1.9 mm-thick plates which experienced large degree of cross rolling, a layer of finer grain was observed in the vicinity of the surface. The NIFS-HEAT-1 products are going through Round-robin tests by Japanese universities.
