Our lab does….

High-fidelity numerical simulation and multi-physics coupling are current research trends in the analysis of nuclear systems. NSSS Lab aims to develop robust methodologies for rigorous treatment of uncertainties, identification of biases, and improved physics modeling for the evolving needs of the reactor physics and thermal-hydraulic fields. Target applications of the methodologies include reactor physics, BEPU, severe accident simulation, passive safety system assessment and design optimization. NSSS Lab also explores new and innovative uses of nuclear science and technology including particle accelerator applications,  alternative reactor coolants, and nuclear forensic techniques in nuclear nonproliferation.
