Abstract
It is known that stress corrosion cracking occurs in stainless steel used as structural materials in high-temperature, high-pressure water at 300°C and 80 atmospheres, as typified by the environment of light water reactor. We have focused on a highly corrosive environment in micro-spaces such as inside a crack, and conducted in-situ measurements of the corrosive environment in a micro-field. By analyzing the measurement results with computational simulation, we have succeeded in clarifying how the corrosive environment is formed and what kind of corrosion may occur.
