DIII-D National Fusion Facility Digital Twin

under development

NVIDIA and General Atomics, with support from UC San Diego, Argonne, and NERSC, have developed a high-fidelity, AI-enabled digital twin for the DIII-D National Fusion Facility fusion reactor. This digital twin integrates sensor data, physics-based simulations, engineering models, and AI surrogate models to create a real-time interactive environment for fusion energy research. It allows researchers to test and optimize reactor designs and control plasma behavior virtually, accelerating the path toward practical commercial fusion energy.
