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.

结果表明，氚水对SUS304不锈钢的腐蚀有明显的钝化抑制作用。这种效应受到pH值、溶解氧浓度和氚浓度的影响。pH值越低，氚浓度越高，对腐蚀行为的影响越大，而去除溶解氧对腐蚀行为的影响不明显。随着氚浓度的增加，引起腐蚀急剧增强的溶解氧浓度增加，导致腐蚀增强。
