About the Lab

Professor Jeong Ik Lee's research lab specializes in advanced nuclear energy systems, with a focus on small modular reactors (SMRs) and supercritical carbon dioxide (S-CO2) power cycles. The lab develops inherently safe, long-life reactor designs using innovative fuels such as uranium carbide and advanced control mechanisms like drum-type control rods. Research directions include modular reactor integration, passive safety features, and applications for decentralized and clean energy generation in small communities. The lab aims to contribute to sustainable energy solutions by replacing aging fossil fuel plants with compact, high-efficiency nuclear systems.

The supercritical CO 2 (S-CO 2 ) Brayton cycle has recently been gaining a lot of attention for application to next generation nuclear reactors. The advantages of the S-CO 2 cycle are high efficiency in the mild turbine inlet temperature region and a small physical footprint with a simple layout, compact turbomachinery , and heat exchangers. Several heat sources including nuclear, fossil fuel, waste heat, and renewable heat sources such as solar thermal or fuel cells are potential application ar
