Abstract

At the time of starting up a nuclear reactor, the concentration of oxidizing substance in a cooling water in a reactor pressure vessel is decreased by evacuating the pressure vessel or replacing air in the vessel with an inert gas for a long time, below a predetermined level before the cooling water is heated to a temperature of 150.degree. C., thereby preventing the occurrence of stress corrosion cracking.
