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.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

One-dimensional two-phase flow equations, describing mass and momentum equations for two phases, are used to analyze viscous term contributions to stability problems concerning two-phase flow equation systems. When viscous terms are taken into account, characteristics of the system become real. This paper shows that viscous terms stabilize disturbances, if the ratio of the system's dimension to the wavelength is sufficiently larger than the Reynolds numbers for the two phases. Some examples show that this result holds, when differential terms are added. An example of stable systems for any wavelength perturbations is given by adding a simple wall shear-like stress term. These results are obtained by the use of a linear stability analysis.
