Abstract

Abstract

The paper conducts the secondary side thermal economy analysis of China improved 3rd Ring Rd Pressurized Water Reactor（CPR1000） nuclear power plant according to the principal method of thermal system calculation. The stream generator of Ling’ao nuclear power plant（phase II）, as an example, is calculated by analyzing the blowdown heat recycling. It is concluded that the thermal economy of the whole unite could be increased by 0.088% if the blowdown heat was recycled by the low pressure heater No. 4.
- Blowdown of the stream generator,
- Thermal recycling,
- Low pressure heater No.4
