As shown in figure 19, existing BWR has thermal source nuclear reactor 200, and in this nuclear reactor 200, the cooling material that is made of light-water is heated back generation water vapour.The water vapour that generates in nuclear reactor 200 is saturated vapor.The water vapour that is generated is given high pressure vapour opinion machine 202 by main steam pipe 201, drives this high pressure vapour opinion machine 202.
Dirty end at high pressure vapour opinion machine 202 is provided with separator 203, and this separator 203 is connected on the pipe arrangement 206 of bleeding of drawing from the heating steam pipe arrangement 204 of main steam pipe 201 branches with from high-pressure turbine 202.Deliver to separator 203 from the exhaust of high-pressure turbine 202 and carry out carbonated drink separation, by the heating steam pipe arrangement 204 and the pipe arrangement 206 of bleeding, heat simultaneously by the high-pressure steam of delivering to separator 203.
Become superheated vapor from the exhaust by the high-pressure turbine 202 of separator 203 heating, this superheated vapor is given low-pressure turbine 205, drives low-pressure turbine 205.High-pressure turbine 202 and low-pressure turbine 205 are by coaxial binding, and these steam turbine are attached on the generator 207 with coaxial simultaneously.Therefore, when high-pressure turbine 202 and low-pressure turbine 205 were driven by water vapour, generator 207 was driven, and generates electricity.
Dirty end at low-pressure turbine 205 is provided with condenser 208, supplies with seawater by circulating water pump (not drawing among the figure) on this condenser 208.Give condenser 208 from the exhaust of low pressure vapour opinion machine 205, being cooled by the seawater in condenser 208 inner loop becomes condensed water.Dirty end at condenser 208 is provided with condenser 209, and at the dirty end of this condenser 209, serial is provided with multistage low-pressure feed heater 210.
And then, be provided with the feed water pump 211 of the driving or power type of turbine at the dirty end of low-pressure feed heater 210, be provided with high-pressure feed-water heater 212 at the dirty end of this feed water pump 211.The pipe arrangement 213 of bleeding that connection high-pressure turbine 202 is drawn on this high-pressure feed-water heater 212, steam pipe arrangement 214 and the sluicing pipe arrangement 215 that separator 203 is drawn.In addition, on low-pressure feed heater 210, connect drain pipe 216 of drawing from high-pressure feed-water heater 212 and the pipe arrangement 217 of bleeding of drawing from low-pressure turbine 205.

But above-mentioned existing power generating equipment is extremely difficult owing to be to utilize the Rankine cycle (ラ Application キ Application サ イ Network Le) of the steam (water vapour) that can condense to generate electricity so improve its thermal efficiency.Particularly because to generate superheated vapor in nuclear energy power generation as thermal power generation very difficult, and be to use saturated vapor, therefore to compare thermal efficiency ratio lower with thermal power generation.
Thereby improving the thermal efficiency in nuclear energy power generation is an important topic, so but owing to have all restrictions also fully not solve.For example drive turbine by about 280 ℃ water vapour in above-mentioned BWR and pressurized water type nuclear energy power generation station (PWR), the thermal efficiency at this moment is about 33%, compares mutually with the thermal power generation that can reach the 40% above thermal efficiency and is on duty.
In order to improve the thermal efficiency of BWR, as long as improve the temperature and pressure of nuclear reactor outlet water vapour, make the efficient of Rankine cycle improve just passable, but problem is when improving the temperature and pressure of water vapour in present saturated vapor circulation, the thermal characteristics of reactor core will worsen, and improve the thickness that withstand voltage properties must increase pressurized container and cooling material pipe arrangement wall.
In order to improve the thermal efficiency of nuclear energy power generation, also can consider on nuclear reactor by generating the temperature that superheated vapor only improves water vapour, but such problem is just must change significantly from existing basis the design of reactor core etc., makes complex structure, the control of the anti-heap of the nuclear difficulty that becomes.
In addition, during nuclear energy power generation, because the steam condition that enters the mouth at turbine is a saturated vapor.So in its inflation process, will produce a large amount of carbonated drink, need take measures to this carbonated drink.Particularly in low-pressure turbine for corrosion of preventing turbine etc., need on its backlimb, adopt the carbonated drink that has the moisture circulation groove to separate the wing, and configuration is efficiently discharged the mechanism of carbonated drink or is taked to dispose the expensive measure that the discharge carbonated drink that is made of Cr-Mo steel is used pipe arrangement from the turbine outer cover.
In addition, low-pressure turbine in nuclear energy power generation, owing to normally under the degree of vacuum about 38mmHg, turn round, so in order to make the acting of expanding be transformed into the rotating energy of turbine, device is maximized, and concerning condenser in order to improve its tightness, to keep its degree of vacuum and just must adopt expensive structure.
Cooling material as nuclear reactor also can use the medium also lower than the boiling point of water to replace present water (light-water) theoretically.But for example ammoniacal liquor is extremely low to the Security of ray for the low boiling medium like this, to decompose by the ray that reactor core sends, produce harmful matter, the problem that the corrosion of promotion nuclear reactor machine occurs, for the processing ray decomposition gas also must increase machine on a large scale, in fact the low boiling medium are impossible to use as the cooling material of nuclear reaction.
