Uniform corrosion penetration prediction model for carbon steel that can be applied in various water quality has been established. It was investigated for the purpose of expanding the knowledge of the corrosion behavior of carbon steel in Fukushima Daiichi nuclear power station of Tokyo Electric Power Holdings Co., Ltd.
The model is applicable to static condition, and flow condition of circular tube. Parameters of the model are temperature, salinity, Larson Skold the Index, average flow velocity and inner diameter of carbon steel tube.
In static water condition, values of corrosion penetration which were predicted by the model were almost the same values as those in the experiments.
In flow conditions in circular tube, values of corrosion penetration which were predicted by the model were within the range from about 0.5 to 2 times of those in the experiments.
