SYSTEM FOR PURIFYING SYSTEM WATER IN SECONDARY SYSTEM OF NUCLEAR POWER PLANT WITH PRESSURIZED WATER REACTOR

摘要

PPROBLEM TO BE SOLVED: To provide a system for purifying system water in the secondary system of a nuclear power plant with a pressurized water reactor which works at lower costs and also has excellent purification performance. PSOLUTION: The system for purifying the system water in the secondary system of the nuclear power plant with the pressurized water reactor has a steam generator 11 to generate steam by vaporizing the system water in the secondary system, a turbine 13 driven by the steam to generate electric power and a condenser 14 to make condensate by cooling the steam that has driven the turbine 13 and is equipped with the secondary system line where the condensate is returned to the steam generator 11 and make-up water supply equipment for purifying raw water with a water purifier 51 and supplying it to the condenser 14. In the system for purifying the system water in the secondary system of the nuclear power plant with the pressurized water reactor, a portion or the whole of blowdown water from the steam generator 11 is returned to the condenser 14 after it is purified with the water purifier 51.
