The author looked for potential mechanisms deemed insignificant in the early stages of SCC research and the current approach used in SCC studies were selected. The basis for those mechanisms was in non-nuclear corrosive environments as well as analyses of redox potential data measured under radiation. Three possible mechanisms were identified; ‘long cell action (which suppresses local cell cathodic activities and accelerates remote local cell anodic activities),’ ‘autocatalytic growth of cracks in crevice water chemistry,’ and ‘transpassive corrosion of stainless steel.’ The ‘long cell action’ has been identified as a key mechanism of soil corrosion which is induced by a difference in the availability of oxygen inside the soil. In this mechanism, conduction of electrons through an electric conductor over a long distance plays a significant role. This author proposes a hypothetical mechanism that states; ‘radiation-induced ‘long cell action’ causing electrolytic corrosion.’
