Summary:PROBLEM TO BE SOLVED: To simplify a facility of an entire plant including a radioactive waste disposal facility by simplifying a facility of a condensate purifying system and to further reduce a generated amount of radioactive waste. SOLUTION: Vapor generated in a nuclear reactor is worked in a turbine 2, then condensed by a condenser 3 of a condensate purifying system, and guided to a feed water system via a low pressure condensate pump 4, condenser filter 5 and a high pressure condensate pump 6. That is, a condensate desalting unit is omitted. Insoluble impurities such as iron clad in the condensate are removed by the filter 5. A coolant purifying system 12 of the reactor is guided from a recirculating system 13 of the reactor, and guided to the reactor via a regenerative heat exchanger 9, non-regenerative heat exchanger 10, filter desalting unit 11 and the exchanger 9. The soluble impurities (ion components) and insoluble impurities in water of the reactor are removed by the unit 11.
