Bridging Neutronics and Thermal-Hydraulics
We focus on developing and optimizing coupled analysis systems that integrate neutronics and thermal-hydraulics. By capturing detailed feedback mechanisms in nuclear reactors using high-fidelity codes (e.g., nTRACER/ESCOT), we aim to ensure precise safety margins for both steady-state and transient conditions.
