Keywords:rotating-type corrosion test, carbon steel, diluted seawater, primary containment vessel

As reported previously, corrosion behavior of carbon steel in the artificial diluted seawater has been examined by the rotating-type corrosion test method and the corrosion rate was accelerated from 3-5 times by the air-solution alternating condition. In this study, an effect of the concentration of diluted seawater at 30ºC will be presented.
