Electrochemical Study on the Effects of Tritium on Corrosion Behavior of Metals

It was clarified from the present study that the corrosion of SUS304 stainless steel was drastically enhanced by the effect of tritiated water named passivation inhibitory effect. This effect came under the influence of pH, dissolved oxygen concentration, and tritium concentration. The lower the pH is and the higher the tritium concentration is, the more the corrosion behavior was affected, while no significant effects could be observed when dissolved oxygen was removed. The dissolved oxygen concentration which can cause the drastic enhancement of corrosion was increased as the tritium concentration increased, resulting in the enhancement of corrosion.
