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.

NEI chief executive highlights “unlimited potential” for nuclear in state of the industry address
Korsnick
In the Nuclear Energy Institute’s annual State of the Nuclear Energy Industry report, NEI president and CEO and Maria Korsnick expressed optimism about the nuclear industry and she issued a call to action.
Her address was part of NEI’s Nuclear Energy Policy forum. The forum, being held in Washington, D.C., on May 20 and May 21, brings together industry leaders, policy stakeholders, and clean energy experts to discuss nuclear advocacy. Korsnick’s remarks focused on the private capital flowing into the industry, progress on regulatory reform and new nuclear technology, and how the U.S. is trying to take the lead on the global nuclear stage.
“We are here at an unprecedented time in our industry history,” Korsnick said. “I’m proud to say that the nuclear industry has a future of unlimited potential.”

Neutron capture and transmission measurements have been carried out upon 182W, 183W, 184W, 186W, 90Zr, 91Zr, 92Zr, and 94Zr over the energy range from ∼150 eV to ≤100 keV at the Rensselaer Polytechnic Institute LINAC Laboratory. Many new resonances have been observed and many resonances, reported previously as singlets, have been resolved into doublets. Most of the resonances that previously eluded observation are assigned to p-wave neutrons. Pertinent resonance parameters have been extracted from the data, and the s-wave and the p-wave strength functions of tungsten and zirconium have been determined from these parameters. The values of the s-wave strength functions in units of 10−4 are: for 182W, 2.60 ± 0.54; for 183W, 2.41 ± 0.48 per spin state; for 184W, 3.0 ± 0.6; for 186W, 2.15 ± 0.46; for 90Zr, 2.0 ± 1.4; for 91Zr, 1.2 ± 0.4 per spin state; for 92Zr, 2.6 ± 1.5, and for 94Zr, 1.0 ± 0.8. The p-wave strength functions in units of 10−4 are: for the even-even tungsten isotopes, ; for 90Zr, 7 ± 4; for 91Zr, 3 ± 2 per spin state; for 92Zr, 7 ± 5, and for 94Zr, 4 ± 2.
