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.

An accurate database is used to study optical model fits to total neutron cross sections of 56Fe in the resolved and unresolved resonance regions. Averages over resolved resonances are calculated from resonance parameters in a Reich-Moore (reduced R matrix) approximation with Lorentzian weighting. Optical potential parameters are obtained for the s, p, and d waves that reproduce the smoothed cross sections in the resolved resonance region. The p-wave optical potential is found to differ from the s-wave potential. When the appropriate higher angular momentum contributions are added, the average total cross sections can be fitted quite well, from the resolved resonance region all the way up to 20 MeV.
