Abstract
Reliability of a cracked pipe much depends on the accuracy both of crack sizing and crack growth assessment. Even if only one of the crack sizing or the crack growth assessment accuracy is improved, the reliability of flaw evaluation does not improve. The influence of these accuracies on reliability was evaluated for the circumferential stress corrosion cracks. The dominated accuracy is crack growth rate, and crack sizing accuracy is negligible.
