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.

A research reactor built in 1962 that was converted to digital control and operation in 2019 is aiding the development of advanced nuclear reactors, such as small modular reactors and microreactors. An article published by Purdue University describes how Purdue University Reactor Number One (PUR-1), currently the only facility to be licensed for a fully digital safety and control system by the Nuclear Regulatory Commission, is being used to perform “first-of-a-kind experiments that are unique to the nuclear sector.”

The American Nuclear Society will be presenting the online Supplier Showcase “5 Critical Approaches to Accelerate Advanced Nuclear Enterprise Success with Digital Transformation” on Thursday, December 5, from 11:00 a.m. to 12:00 p.m. (EST). The session will be hosted by Dassault Systèmes.

Registration for the program, which is open to all, is required.

Researchers at Idaho National Laboratory (INL) recently performed their first digital twin test of the Microreactor Agile Non-nuclear Experimental Testbed (MAGNET) and captured the demonstration in a video posted July 14. The digital twin—a virtual representation of a microreactor—was built using advancements in remote monitoring, autonomous control, and predictive capabilities that could help lower operating costs of microreactor technologies and enhance their safety.
