PROBLEM TO BE SOLVED: To provide a method and device for preventing corrosion in a nuclear reactor structural material, being further improved in corrosion prevention without causing secondary problems when preventing the corrosion of the structural material. SOLUTION: In the corrosion preventing method for the nuclear reactor structural material, corrosion potential of structural members is lowered by supplying hydrogen to at least one system among a reactor recirculation system 4, a residual heat removal system 5, a reactor coolant purification system 6, and a water supply system 7. When supplying hydrogen from hydrogen supplying devices 16a, 16b... provided in at least one of the systems, the concentrations of hydrogen, oxygen, etc. contained in water are calculated and analyzed by a hydrogen analyzer 17 to set the supplied amount of hydrogen based on data acquired through the calculation and analysis.
