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.

President's Profile Steven Arndt: Prioritizing participation and advocacy
Steven Arndt began his one-year term last month as president of the American Nuclear Society, bringing the same high level of energy, investment, and action he has exhibited throughout his career. Reflecting on a life spent improving nuclear safety and technology, he notes that it’s not just the work; it’s also about the people and building connections and relationships. Arndt fondly recalls Peter Lyons, former NRC commissioner, assistant secretary of energy for nuclear energy, and ANS board member who passed away in April 2021. “I have been incredibly lucky to know and work with some great people in our field, and almost to a person they have been like Pete Lyons,” Arndt said. “They have been gregarious, outgoing, and supportive.”
