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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

Transmission measurements on samples of natural tungsten (W) and samples enriched in 184W have been made with the ORNL fast-chopper time-of-flight spectrometer. The measurements were made at the 180-m flight station with a resolution of ≈ 10 nsec/m between 40 and 10 000 eV, and at the 45-m station with an energy resolution from 0.7 to 1.5% between 0.2 and 100 eV. The transmission data have been analyzed to give the parameters for 16 resonances in 184W up to 2100 eV. From these parameters the following data for 184W have been determined: an average neutron level spacing of 110 ± 30 eV, an s-wave neutron strength function of (3.1 ±1.1) × 10 −4, and a radiative-capture resonance integral of 12 ± 2 b.
