6. a kind of multi-stage heat presurized water reactor circulating generation method according to claim 5, which is characterized in that in step S1,
The high temperature and high pressure gas medium of heat exchanger tube discharge enters in the first water pot gas compartment of first order heating power presurized water reactor, drives first
Piston carries out compression movement to fluid space in water pot, and the liquid in the first water pot fluid space is extruded by piston and enters water wheels
It does work in generator, the second water pot liquid of the liquid reflux in hydrogenerator after acting to first order heating power presurized water reactor
In space, and gas compartment compression movement of the second water pot inner piston to the second water pot is driven, by the gas compartment in the second water pot
Gas medium extrude and successively by steam turbine, compressor, flow back into and carry out increasing temperature and pressure in the heat exchanger tube in boiler；
In the second water pot gas compartment that the high temperature and high pressure gas medium of heat exchanger tube discharge enters first order heating power presurized water reactor, drive
Piston is set in the second water pot to carry out compression movement to fluid space, the liquid in the second water pot fluid space is gone forward side by side by piston extrusion
Enter in hydrogenerator and does work, the first water of the liquid reflux in hydrogenerator after acting to first order heating power presurized water reactor
In tank fluid space, and gas compartment compression movement of the first water pot inner piston to the first water pot is driven, by gas in the first water pot
The gas medium in body space extrudes and successively passes through steam turbine, compressor, flows back into the heat exchanger tube in boiler and carries out heating liter
Pressure；
So circulation, realization is continual to provide operation power for steam turbine, hydrogenerator.
7. a kind of multi-stage heat presurized water reactor circulating generation method according to claim 6, which is characterized in that in step S3,
The structure of second level heating power presurized water reactor is identical as first order heating power presurized water reactor；Steam and liquid in the heating power presurized water reactor of the second level
Liquid flow process in space is identical as in step S1.
