A plurality of detectors for detecting the quality of the condensate and/or detection ports for taking out a sample of the condensate are provided in the hot well zone. The control valve is provided on a feed water system for adjusting the supply of the condensate to be supplied from the condenser to the feed water system on the basis of water quality detection values detected by the plurality of detectors and/or detection ports and a make-up water system is provided for supplying make-up water to the feed water system on the downstream side of the control valve.
