<P>PROBLEM TO BE SOLVED: To provide a corrosion inhibition method for a plant and a plant that may cut down equipment cost and operating cost. <P>SOLUTION: A pressurized water type nuclear power plant includes a steam generator 2, turbines 3 and 5, a condenser 6, and heaters 7 and 8. In a secondary system of the pressurized water type nuclear power plant, non-deaerating treated water circulates without deairing process by a deaerator or chemical infusion by a chemical injector. A protective substance which is composed of TiO<SB POS="POST">2</SB>, Y<SB POS="POST">2</SB>O<SB POS="POST">3</SB>, or La<SB POS="POST">2</SB>O<SB POS="POST">3</SB>is applied to a structural material of the system where the non-deaerating treated water contacts. <P>COPYRIGHT: (C)2012,JPO&INPIT |
