Validity study and the configuration of the supercritical CO2 Brayton cycle

A closed Brayton cycle with the use of supercritical CO2 (S-CO2) as the working fluid is studied. Recently, the research on the power cycle for a next generation reactor has been conducted and the S-CO2 Brayton cycle is presented as a promising alternative for the present Rankine cycle. As an advanced power conversion system, the S-CO2 Brayton Cycle has many advantages. The principal advantage is a lower compression work compared to an ideal gas such as helium. As a result, a good efficiency at a modest temperature, a simplified compressor design and a compact size of the heat exchangers and turbines are achieved. The S-CO2 Brayton cycle coupled to KALIMER (Korean Advanced Liquid Metal Reactor) excludes the possibilities of SWR (Sodium-Water Reaction) which is the major safety-related event, so that the safety of KALIMER can be improved. The validity study and the configuration of the BOP and the optimization of the design parameters are being carried out
