The goal is to improve turbulence modeling, which helps researchers predict complex fluid behavior and its effects on reactor systems. Transformers tackle reactor turbulence In nuclear reactors, understanding fluid movement is critical because fluids transport heat and interact with components throughout the plant. Digital twins enter nuclear simulations The researchers’ next step is to apply the model to simulations of entire power plants. Argonne researchers say they are among the first to explore transformer architectures for digital twin technology in nuclear systems. Combined with faster simulation models, the technology could provide another tool for studying plant performance and identifying potential issues.
