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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.”

Capture, elastic scattering, and total cross-section measurements were performed on 237Np between 8 and 204 eV. The neutron widths, Γn, were obtained for 200 resonances and the radioactive widths, Γγ, for 25 resonances. The mean capture width <Γγ> = 41.2 ± 2.9 meV, and the mean s-wave resonance spacing D0 = 0.740 ± 0.061 eV. The s-wave strength function was found to be S0 = (1.02 ± 0.14) × 10−4.
