Research of Supercritical Carbon Dioxide Thermal Power System Based on Lead-Cooled Fast Reactor


 The supercritical carbon dioxide (S-CO2) Brayton cycle with re-compression has the advantages of compact layout, simple structure, thermal high efficiency, clean working quality, its application in lead-cooled fast reactor power conversion system helps the miniaturization and modularization of the whole system. In addition, it is considered to be an effective solution to the problem of the recuperator point for the lead-cooled fast reactor power system. The Aspen plus software was applied in this paper to establish the mathematical model for supercritical carbon dioxide Brayton cycle with re-compression and the 1MWe lead-cooled fast reactor power system was calculated. The effects of several key factors such as the turbine inlet temperature, the turbine inlet pressure, the efficiency of the turbine, compressor and recuperator were analyzed. The results show that the turbine inlet pressure, the turbine inlet temperature and the turbine efficiency have remarkable effects on thermal efficiency of the system. Thermal efficiency of the system increases with the inlet pressure, inlet temperature and efficiency of the turbine increasing. The research results of this paper could provide important theoretical reference both for thermal cycle parameters for 1MWe lead-cooled fast reactor and system design of power cycle based on the lead-cooled fast reactor.
