Engineering Design of Supercritical Brayton Cycle
Small modular reactors (SMRs) tend to emerge these days as a viable option to meet energy requirements at a remote site. Since the SMR requires higher thermodynamic cycle efficiency, the supercritical Brayton cycle power conversion system becomes a commanding option for future applications. It is expected that the Brayton cycle have higher thermal efficiency than the commercial Rankine cycle. Besides, the volume of the whole cycle is expected to be reduced by adoption of supercritical fluid that has higher density than gases. The cycle efficiency is obtained according to the arrangement of components. Moreover, the power conversion system must necessarily be optimized. In order to achieve these requirements, a first-principle system code Optimized Supercritical Cycle Analysis (OSCA) is being developed to optimize the design of the supercritical fluid driven Brayton cycle for the small power conversion system. This code is based on the recompression Brayton cycle. The supercritical carbon dioxide is adopted as the working fluid for power conversion system because of its easy acquisition, high density and low chemical reactivity.
