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.

Christopher Perfetti, assistant professor at the University of New Mexico, will analyze the Chernobyl accident from the viewpoint of a reactor physicist. He will explore the physical mechanisms that led to Chernobyl's runaway chain reaction and will explain why they are not possible in modern reactors. In addition, he will:
This presentation will provide a valuable understanding of reactor physics, and will also provide enough interesting information about Chernobyl to appeal to seasoned reactor physicists.
