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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Over the past few years a number of experiments have been carried out at LLNL with a scintillator array that has the ability to count individual MeV neutrons and -rays with nanosecond timing. It has been demonstrated that this array can be used to measure the statistical properties of the neutrons emitted in single fission chains. The multiple time scales over which these fission neutrons are correlated allow one to deduce quite a lot regarding the nature of the fissile assembly. In this paper we will describe how neutron correlations measured with a liquid scintillator array can be used to assay the amounts of fissile elements in reprocessed and spent nuclear fuels.
