Abstract

The invention discloses a lead-cooled fast reactor supercritical carbon dioxide cycle switchable ship power system, comprising a lead-cooled fast reactor and a stack chamber composed of a primary circuit system, and a switchable supercritical carbon dioxide power cycle secondary circuit system. Engine room and propulsion device; the lead-cooled fast neutron reactor is used as the heat source, and the supercritical carbon dioxide power cycle combining primary reheating, intercooling compression and split recompression processes is used to output the ship's propulsion power and equipment power, which is realized by the opening and closing operation of the gate valve. Effective switching of supercritical carbon dioxide cycle between internal cooling mode and partial cooling mode under different operating requirements, and combined with direct propulsion to drive the ship to sail. The energy conversion efficiency of the invention is significantly improved, the compactness of the power plant and the payload of the ship are greatly improved, the low energy consumption and high-performance operation of the ship are satisfied, and the application of the supercritical carbon dioxide cycle in the field of nuclear power ships is provided. new ideas.

Description

technical field [0001] The invention relates to a ship power system, in particular to a lead-cooled fast reactor supercritical carbon dioxide cycle switchable ship power system. Background technique [0002] The equipment research and development and technological upgrading of the power system of large ships is the top priority of coastal defense development, and the use of nuclear reactors to provide power is a clear development direction in the future. At present, the power plant of the pressurized water reactor combined with the steam cycle commonly used in large ships has a low thermal efficiency (about 33%), and its further improvement is limited and the equipment scale is large. Therefore, the active development of high-efficiency and compact new power units is of great significance for improving the overall performance of ships and leading technological changes. SUMMARY OF THE INVENTION [0003] Purpose of the invention: The purpose of the present invention is to p...
