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.

Thanks to the generous US DOE NNSA support, we have a number of travel grants for undergraduate and graduate students. Preference will be given to whose who are presenting. To apply please submit your abstract and then send an email containing your name, affiliation (university), abstract number, and abstract title to Dr. Valeriia Starovoitova.
The fourteenth international topical meeting on the applications of accelerators (AccApp'20) was originally planned to be held at the IAEA Headquarters in Vienna, Austria, April 5-9, 2020. The meeting was postponed because of COVID-19.
The AccApp'20 was organized by Dr. Philip Cole (General Chair, Lamar University), Dr. Aliz Simon (General Co-Chair, IAEA), and Dr. Valeriia Starovoitova (Co-Chair, and Technical Program Chair, IAEA), together with 22 topic organizers.
AccApp'20 received total 320 abstracts from 58 countries. AccApp'20 was sponsored by seven industry companies, as well as IAEA and US DOE-NNSA.
