摘要： PURPOSE:To avoid using highly moist steam which is a factor in pipe corrosion, so as to enable economical carbon steel to be used by building a system in order to use reheated steam drawn out immediately from the way-out of a reheater as a source of heated steam supply of a water supply heater. CONSTITUTION:In the case of a reheating-type atomic power plant, highly moist steam which makes work in a high pressure turbin 2, is made free from moisture through a moisture separator 3, then reheated by the first-step and the second-step reheaters 12a, 12b, and flows into a low pressure turbine 4. Then, the air drawn out of the high pressure turbine 2 is supplied as heating steam 14b for a high pressure water supply heater 11b, and so is super-heated steam in the way-out of the second-step reheater 12b as heating steam 14a for a high pressure water supply heater 11a. Similarly, the air drawn out of a low pressure turbine 4 is supplied as heating steam 13a-13d for low pressure water supply heaters 9a-9d. Factors in pipe corrosion are excluded by the above mechanism, and carbon steel can be used for piping and the cost of equipment can be reduced.

摘要： PURPOSE:To enable an improvement of the water quality in condensation by a method wherein a condensating and desalting device is provided in a main system on the downstream side of a condensation pump so as to reduce a zone in the condensation system to be led to a nuclear reactor without passing the water through a condensing and scavenging device. CONSTITUTION:Waste steam from a steam turbine and drain from a water supplying and heating device are condensed in a condenser 1 and sent as a condensate to a first hot well 2. The pressure of the condensate is increased by a condensation and scavenging circulation pump 3 and then the condensate is sent to a condensing and filtering device 6 to undergo a water quality treatment so as to remove corrosive products therefrom. Then, after heat exchanged by a grand steam condenser 8 and an air extractor 9, the condensate is sent to a suction header 13 of a condensation pump 15 through a level control valve 12 so that the level in a middle tank 11 is stabilized. The condensate is sent to the main system by the condensation pump 15 is treated to remove corrosive products therefrom. Further, after the temperature is increased by the water supplying and heating device in the water supply downstream, the condensate is supplied to the nuclear reactor 20.
