ISCC properties of zircaloy-4 cladding

Description

An equipment of inducing an internal, longitudinal fatigue crack in a tube was designed and manufactured. Using this equipment, the zircaloy-4 specimens which had been fatigue-cracked at internal surface for evaluating their iodine-induced stress corrosion cracking (ISSC), were prepared. Tube pressurization tests were conducted at 623 .deg. K and the iodine concentration of 10-3 g/cm2. The K1, (stress intensity factor) and crack propagation velocity were evaluated using the depth of ISCC crack measured by scanning electron microscope (SEM). From the relationship between the K1 and crack propagation velocity, KISCC (threshold stress intensity factor) of zircaloy-4 cladding was estimated
