The invention belongs to the technical field of nuclear power units, and particularly discloses a system of an integrated small reactor nuclear power unit and a reactor operation method, and the system comprises an integrated reactor, a steam turbine generator unit, a main control system and the reactor operation method. The integrated reactor comprises a pressure vessel, a steam-water separator and a normal residual heat removal system; a reactor control rod driving mechanism and a straight-flow type steam generator are arranged in the pressure vessel, and an outlet of the straight-flow type steam generator is connected with an inlet of a steam-water separator; an inlet and an outlet of the normal residual heat removal system are connected with a primary loop pipeline of the reactor core; the steam turbine generator unit comprises a steam turbine inlet steam regulating valve, a steam turbine, a condenser, a condensate pump, a deaerator, a water feeding pump, a water feeding regulating valve, a bypass steam discharge valve, a separator drain discharge valve and a generator. The system can meet the internal and external requirements in the unit power operation stage and the starting and stopping process, and has the capacity of rapidly adjusting the unit output power.
Description
technical field [0001] The invention relates to the technical field of nuclear power units, in particular to an integrated small reactor nuclear power unit system and a reactor operation method. Background technique [0002] In recent years, with the continuous development of nuclear energy technology, the integrated small reactor nuclear motor composition has become a new way of nuclear energy utilization. Compared with traditional fossil energy, nuclear energy has the advantages of low fuel cost, long refueling cycle, good operation stability, no pollutant emission, and nuclear reaction does not require oxygen to participate. Therefore, integrated small reactors have a broad application space for island power generation, offshore oil drilling platforms, icebreakers, deep-sea submersibles and other scientific research facilities or military and civilian equipment. [0003] Compared with the traditional large pressurized water reactor commercial nuclear power plant, the int...
