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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

The statistical method for calculating neutron cross sections in the unresolved resonance region has been extended to permit the construction of ladders for higher angular momentum neutrons and for all accessible spin states (and substates) of the compound nucleus. The new method is an improvement over existing methods in that a fitting procedure is adopted to ensure that the constructed sequence of resonances reproduces resonance integrals inferred from low-resolution experimental results. The s- and p-wave components of the capture cross section of 238U have been computed between 4 and 80 keV using a sequence of resonances obtained by fitting over the energy range 4 to 15 keV. The calculated 238U capture cross section is in excellent agreement with published data in the energy range 25 to 60 keV.
