A 3D-FEM simulation code based on the deformation/oxidation model for the evaluation of SCC in comp act tension specimens was extended to evaluate the axial SCC behavior of mock-up specimens of botto m mount instrumentation tube of pressurized water reactor, and its applicability was investigated by comparing the cracking behavior calculated by the simulation with that obtained by the experiment....

Stress Corrosion Cracking Test Methodology for inner axial cracks and its cracking behavior

Continuous monitoring of stress corrosion cracking (SCC) in chloride solution containing thiosulfate was performed using type 304 stainless steel pipe specimen with weldments. Induced Current Potentia l Drop (ICPD) method was used to the continuous monitoring of the SCC growth. The ICPD method permit s continuous monitoring of the SCC growth which initiates from the inner wall of the pipe specimen....

Continuous Monitoring of Stress Corrosion Cracking Growth in Type 304 Stainless Steel Pipe Weldments using Potential Drop Method.

The test methodology using specimens in the shape of tubes was developed to create axial SCCs on the inner w all of the specimen, and its effectiveness was verified by performing SCC tests under LWR environment. It w as shown that the axial stress corrosion cracking was generated from the deepest point of pre-crack by modif ying the loading mode, though the crack was not created around the loading point due to compressive stress....
