    The invention discloses a supercritical carbon dioxide circulation switchable vessel power system of a lead-cooled fast reactor. The supercritical carbon dioxide circulation switchable vessel power system comprises the lead-cooled fast reactor, a reactor cabin composed of a primary loop system of the lead-cooled fast reactor, a cabin composed of a switchable supercritical carbon dioxide power circulation secondary loop system and a propelling device. A lead-cooled fast neutron reactor is adopted as a heat source, and ship propulsion power and equipment electric power are output in a supercritical carbon dioxide power cycle mode combining primary reheating, intermediate cooling compression and shunt recompression processes. Effective switching of supercritical carbon dioxide circulation ofan inner cooling mode and a partial cooling mode under different operation requirements is achieved through gate valve opening and closing operation, and the direct propelling device is combined to drive the vessel to sail. The energy conversion efficiency is remarkably improved, the compactness of the power device and the effective load of the vessel are greatly improved, low-energy-consumption and high-performance operation of the vessel is satisfied; according to the invention, a new thought is provided for application of supercritical carbon dioxide circulation in the field of nuclear power vessels.
