PROBLEM TO BE SOLVED: To control corrosion of metallic materials in a super-critical pressure light water reactor using a direct cycle, reduce transfer of radioactive corrosion products to a turbine system and reduce the dose of the turbine system. SOLUTION: Oxidation treatment using high-temperature water or high-temperature steam is applied on at least part of the surface of a solid metallic material in contact with a coolant in the super-critical pressure light water reactor. The surface of the solid metallic material as an object of oxidation treatment may be mechanically polished or electrolytically polished before the oxidation treatment. Preferably, high-temperature water containing at least one of Ni, Zn, Fe, Cr, Mn, Cu, Pd, Pt, Al, Mo, V and W is used for the oxidation treatment. COPYRIGHT: (C)2008,JPO&INPIT
