Establishment and Amendment of Test Standards for Evaluating Stress Corrosion Cracking Initiation in High temperature Water

Abstract

Because of lack of test standards applicable in high-purity water at high temperatures, standardization of test methods for evaluating the stress corrosion cracking initiation of metals and alloys used for nuclear power plant has been carried out. The standard of uniaxial constant load test method has been established and stipulated in JSCE standard （JSCE S 1501）. The Japan industry standard （JIS G 0511） has been reviewed and modified for the rationalization of reverse U-bend test method. Furthermore, the attempt to reflect these discussed technical resolutions in ISO standard is currently ongoing.
