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.
Speakers will show slides by using USB drives with the conference-provided laptop. Session chairs and speakers cannot use their own laptops; the conference-provided laptop must be used. Suggest to presenters that they email the slides to themselves and upload them to the meeting platform as back-ups.
Speakers know to check in with you in your session room at least 15 minutes before the start of your session. They may present you with brief biographical information to aid in your introductions. Or, before the conference, you can ask speakers to provide you with brief bios for introductions.
Assist presenters in keeping track of their time so that presentations do not run over. Please do not rearrange the order of the presentations in your session.
If your session is in the first morning timeslot, a session sign will be placed by the room approximately 20 minutes before the session begins. For all other timeslots, the session sign will be in place.
Start your session with a quick introduction.
If you have a no-show, hold that time slot, and do not move ahead. Consider prompting discussion about the session’s topic to fill the time and to encourage attendees to remain in the room.
Inform ANS Registration/Help Desk of any no-shows in your session or you can email epsr@ans.org to report no-shows.
Remind attendees who request Professional Development Hours (PDHs) that they must complete the in-app session survey.
