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.

High flux level reaction rates are measured from the gamma-ray emission analysis of activated foils. These foils are analyzed nondestruc-tively to eliminate error due to dissolution, dilution, and/or chemical separation. Signal-to-noise enhancement is achieved through the exclusive use of lithium-drifted germanium detectors, always with high peak-to-Compton ratios and occasionally with active Compton suppression. The reduction of the gamma-ray spectral data to accurate reaction rates as performed in three independent laboratories is categorized to illustrate the areas of potential pitfalls and the diversity of approaches used in successfully avoiding them. The estimated absolute errors and the range of results among the laboratories have been reduced below the target value of ±10% (2σ) for nonfission foils and is approaching the target value of ±5% (2σ) for fission foils.
