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.

Most advanced reactor designers plan to use high-assay low-enriched uranium (HALEU) fuel, including the two reactors selected by DOE’s Advanced Reactor Demonstration Program. Moreover, some utilities seek to use slightly higher enrichments in existing light-water reactors. However, there is an insufficient supply of HALEU to supply demonstration reactor needs, no domestic HALEU enrichment capability, and significant uncertainty surrounding long-term HALEU demands. To address these challenges, DOE has been down blending high-enriched uranium and has solicited input on a HALEU Availability Program. In addition, several enrichment companies have established HALEU programs. At this panel, panelists from the enrichment industry and government discuss the status and next steps for establishing a domestic HALEU fuel supply chain. Establishing domestic HALEU production capability will enable the US to expand its position in the global nuclear energy market while promoting its own nonproliferation agenda.
