Day 1-3A-STEWART - Leveraging Digital Twins for Autonomous Operations.pdf

1、Leveraging Digital Twins for Autonomous OperationsOctober 6th,2025Ryan StewartData ScientistWhat are Digital Twins?“A digital twin is an integrated data-driven virtual representation of real-world entities and processes,with synchronized interaction at a specified frequency and fidelity”Digital Twin

2、 ConsortiumDigital engineering transforms the way we design and operate energy assets:1.Semi-autonomous design,autonomous operation,and real-time anomaly detection2.Drives research across compute platforms with human centered visualization3.Integrates threads of data,visualizations,AI/ML,and physics

3、 modelsOverviewDeveloping CapabilitiesDigital Twin DemonstrationTowards Autonomous OperationsAGN-201 Digital Twin Overview Goal:Determine if a digital twin of a research reactor can be used to detect anomalies which may indicate off-normal operations Impact:Can a digital twin be used at the Internat

4、ional Atomic Energy Agency(IAEA)to help facilitate automated reactor monitoring to ensure international safeguards Outcome:Over one-year,developed a digital twin of a nuclear research reactor and was successfully demonstrated with a red/blue team testOverviewDeveloping CapabilitiesDigital Twin Demon

5、strationTowards Autonomous OperationsAGN-201 Digital Twin Reactor The AGN-201 is a 5 W reactor Nine fuel disks of polyethylene with uranium dioxide compose the core Graphite,lead,and water surround core(neutron/gamma shield)Four control fueled control rods Fine control rod&coarse control rod control
