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.
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.

Finland in Front: The World’s Likely First Spent Fuel Repository Moves Toward Licensing
The year 2024 is shaping up to be a historic one for Posiva, the waste management organization owned by Finland’s two nuclear power plant utilities, Fortum and Teollisuuden Voima. The company is looking to receive regulatory approval of its operating license for the Onkalo deep geological repository for high-level radioactive waste by the end of the year.

The neutron reaction data of 181Ta for the incident energy up to 200 MeV are urgently required for the study of nuclear reactor systems of fission or fusion. To meet this requirement, all cross sections, angular distributions, energy spectra, and double-differential cross sections for n + 180m,181Ta reactions are consistently calculated and analyzed at incident neutron energies up to 200 MeV. The theoretical results are compared with the experimental data and the evaluated results in ENDF/B-VIII, JENDL-4, and JEFF-3.
