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.

BREAKING NEWS: Trump issues executive orders to overhaul nuclear industry
The Trump administration issued four executive orders today aimed at boosting domestic nuclear deployment ahead of significant growth in projected energy demand in the coming decades.
During a live signing in the Oval Office, President Donald Trump called nuclear “a hot industry,” adding, “It’s a brilliant industry. [But] you’ve got to do it right. It’s become very safe and environmental.”

Consistent calculation and analysis of neutron scattering data of 233,235,237U with optical model, semiclassical model including both the unified Hauser-Feshbach theory and the exciton model, the coupled channel theory, and distorted wave Born approximation were carried out in the En 20-MeV energy range based on the experimental data. In particular, the analysis includes the prompt fission neutron spectra and the double-differential cross section for neutron emission. Theoretical calculations are compared with recent experimental data and other evaluated data from ENDF/B-VI release 6 and JENDL-3.3.
