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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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?

Single-electron-capture cross sections 10 for W+ projectile ions on Ar and Kr atomic gas targets at 10 keV (55 eV/u) and on H2, D2, CH4, C2H6, and C3H8 molecular gas targets at between 5.0 and 10 keV (27 and 55 eV/u) were experimentally derived for the first time. With our published single-electron-capture cross sections q q-1 for Beq+, Bq+, Cq+ , Feq+ , Niq+ , and Wq+ (q = 1 for Fe; q = 1,2 for the others) ions in low energy, an attempt was made to draw scaling behavior of single-electron-capture cross sections for such slow low-q ions on target species. Established scaling formulas are found to reproduce the measured cross sections generally within a magnitude and with higher precision for specific initial charge state and target species.
