[2M09] Anodic polarization simulation of structural materials of recirculation piping
Keywords:Computational chemistry, Corrosion, Stainless steel, BWR
In order to set the corrosion rate according to the corrosion environment used in BWR radionuclide behavior evaluation model, we developed an simulator which calculates anodic polarization curves of structural materials of recirculation piping. This simulator was constructed to solve the electrochemical reaction equations and diffusion equations in the one-directional model of which the direction is normal to the surface. Experimental anodic polarization behavior of stainless steels in pure water were successfully reproduced by the simulator.
