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.
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 Ubiquity of PFAS: An Emerging Issue in Decommissioning
Per- and polyfluoroalkyl substances (PFAS), an anthropogenic class of several thousand chemicals made for use in products such as nonstick cookware, water-, grease-, and stain-resistant materials, surfactants, and fire suppression foams , are emerging as a complicating factor in nuclear decommissioning. These chemicals, which have been manufactured globally, including in the United States, have gained regulatory and public attention due to their persistence and ubiquity in the environment, ability to be detected at low parts-per-trillion levels, and health-based standards set at levels hundreds to thousands of times lower than more classic contaminants such as polychlorinated biphenyls (PCBs).

During the 20 years the Graphite Reactor operated—from 1943 to 1963—it continued its pioneering role. It is the oldest reactor in the world. Watch and read more.
Note: Because of the construction close to the GR, the bus will have to drop guests off at the bottom of Hill Avenue, about a 2–3-minute walk up the hill. Please consider.
