The supercritical carbon dioxide system has great application prospects in gas-cooled fast reactors,lead-cooled fast reactors and sodium-cooled fast reactors. The research status and related progress of supercritical carbon dioxide power cycle system and its key components in sodium cooled fast reactor are reviewed. Combined with the heat source characteristics of sodium cooled fast reactor,the typical supercritical carbon dioxide power cycle structure,printed circuit board heat transfer are respectively studied. The heat transfer characteristic coefficient,the selection of S-CO2 compressor and turbine type,and the key characteristics of bearing and seal are summarized and analyzed,which provide reference and basis for the following S-CO2 Brayton cycle for sodium cooled fast reactor design and prototype development.
