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.
Meeting Spotlight

Fission fragments anisotropy in fast-neutron-induced fission of 235U was measured at neutron energies ranging from 0.3 to 1.4 MeV at intervals of 0.1, 1.6, 1.8, and 2.2 MeV. In the present study, the pairing energy gap (2Δ0) for the highly deformed transition state of the nucleus 236U was found to be 2.0 ± 0.06 MeV.
