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.

NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

Several polycarbonate plastics and cellulose nitrate have been studied for radiographic imaging studies with alpha particles, protons, fast neutrons, and thermal neutrons. Comparisons, made with conventional film-detection methods in terms of exposure requirements, spatial resolution, contrast, and convenience, show that track-etch techniques can give comparable or better results. Comprehensive results for thermal-neutron radiography indicate that total thermal-neutron exposures in the range of 2 × 107 to 4 × 108 n/cm2 provide radiographs which display a contrast sensitivity of 1 to 3% and a spatial resolution of ∼25 μm. A scattered-light enlargement technique provides a simple means to improve visual contrast of track-etch images.
