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.

Purdue’s research reactor aids in advanced reactor development
A research reactor built in 1962 that was converted to digital control and operation in 2019 is aiding the development of advanced nuclear reactors, such as small modular reactors and microreactors. An article published by Purdue University describes how Purdue University Reactor Number One (PUR-1), currently the only facility to be licensed for a fully digital safety and control system by the Nuclear Regulatory Commission, is being used to perform “first-of-a-kind experiments that are unique to the nuclear sector.”

Muon loss to side cycles of muon catalyzed fusion is discussed in a schematic model. Experimentally extracted values for permanent muon loss probability (“muon sticking”) depend on the presence of cycles terminating by formation of unobservable low-energy neutrons.
