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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Proton radiography imaging qualities have been studied using Monte Carlo simulations. A specific phantom, made of different common tissues, was implemented for simulations using the Massachusetts General Hospital treatment proton beam, pure 230- and 490-MeV proton beams, and a pure 100-keV X-ray beam. Along with spatial resolution, the signal-to-noise ratio and the contrast-to-noise ratio were specified and compared for each tissue type and geometry, using filtered radiographs taking into account only primary proton interactions, both primary and secondary proton interactions, and both contributions while performing angular and energetic cuts. This work particularly highlights the faculty for proton radiography to image both low- and high-density tissues. This could play an important role in diagnosing specific tumor types, such as lung cancer, for which conventional radiography operates poorly.
