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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

A new capsule design was prepared and tested at the High Flux Advanced Neutron Application Reactor (HANARO) for neutron irradiation of the core materials of research reactors at a low temperature (of <100°C). The capsule was first designed at HANARO to have the coolant flow through the capsule to cool down the irradiation temperature of the specimens. The safety of the newly designed capsule should be fully checked before irradiation testing. Out-pile performance and endurance testing before HANARO irradiation testing was performed using a capsule in the HANARO out-pile test facilities. The new capsule had a much higher coolant flow-induced vibration than a standard capsule, resulting in fatigue failure at the rod tip of the capsule. The lifetime of the rod tip was greatly improved by changing the material from Type 304 stainless steel to Type 316L stainless steel and by changing the welding method from tungsten inert gas welding to electron beam welding. With the optimized design, the capsule was successfully irradiated at low temperatures of <100°C for up to eight cycles (6075 MWd) at HANARO.
