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.

Argonne creates new methodology for digital twins
Hu
Argonne National Laboratory has added a new twist to digital twin technology for research into nuclear energy. According to Rui Hu, a principal nuclear engineer at Argonne, “Our digital twin technology introduces a significant step toward understanding and managing advanced nuclear reactors, enabling us to predict and respond to changes with the required speed and accuracy.”
The research of Hu and his colleagues, “Development of Whole System Digital Twins for Advanced Reactors: Leveraging Graph Neural Networks and SAM Simulations,” was published in the American Nuclear Society journal Nuclear Technology.
Virtual representation: A digital twin technology is an accurate virtual representation of a complex system. It is updated with real-time data from sensors applied to the physical system, such as a nuclear reactor.
Stand with us in support of the brave workers and their families within Ukraine’s nuclear community.
An appeal from the Ukrainian Nuclear Society.
Help Ukraine Get Through Winter
Ukraine’s power grid is under attack. Russian airstrikes have destroyed over nine gigawatts of capacity, leaving the country with only a third of the power needed to meet peak winter demand. Daily blackouts of up to 20 hours and heating fuel shortages can mean life or death for many. Urgent help is needed.
Stand with us in helping Ukraine’s “frontline” nuclear communities stay warm this winter.
Give to the ANS-ENS Ukrainian Nuclear Workers Humanitarian Fund and help Ukraine’s nuclear communities in need across the country, from satellite cities that host nuclear power plants to communities that host specialized higher education institutions and nuclear research facilities.
In partnership with the European Nuclear Society (ENS), all donations go directly to the Ukrainian Nuclear Society for the purchase and distribution of essential medical supplies, personal protective equipment, batteries, flashlights, warm clothes, food, and other items.
The American Nuclear Society is a 501(c)3 not-for-profit organization. Your contribution is tax-deductible to the extent allowed by law.
