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.

Japanese researchers test detection devices at West Valley
Two research scientists from Japan’s Kyoto University and Kochi University of Technology visited the West Valley Demonstration Project in western New York state earlier this fall to test their novel radiation detectors, the Department of Energy’s Office of Environmental Management announced on November 19.

Monoenergetic gamma beams (Δ ~ 10 eV) based on thermal neutron capture, in a nuclear reactor, using the V(n,γ) and Fe(n,γ) reactions were utilized for generating fast neutron sources from lead and thallium, respectively, via the 207Pb(γ,n) and 205Tl(γ,n) reactions. It so happens that one of the incident gamma lines of the V source, Eγ = 7163 keV, photoexcites by chance a resonance level in 207Pb, which emits neutrons at an energy of 423 keV. In a similar manner the incident gamma line at Eγ = 7646 keV of the Fe(n,γ) source photoexcites by chance a resonance level in the 205Tl isotope, which emits neutrons at an energy of 99 keV. The cross sections for the neutron emission process were measured and found to be σ(γ,n) = 35 ± 6 mb and 107 ± 17 mb, respectively, with intensities of the order of 104 n/s.
