Abstract
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 areas of the S-CO 2 cycle. In this paper, the current development progress of the S-CO 2 cycle is introduced. Moreover, a quick comparison of various S-CO 2 layouts is presented in terms of cycle performance.
