“…To validate that the correlation developed to predict the ligament rupture pressure of PTW EDM flaws in straight tubes can be used to predict the ligament rupture pressure of PTW axial ODSCC, five axial ODSCC specimens were fabricated using straight tubes with and without wear marks are discussed further in the "Manufacturing of Representative Axial Stress Corrosion Cracks in Tube Specimens," report by Bahn et al [11]. Eventually, 28 ODSCC specimens were fabricated from tubes; 19 from tubes without wear marks (Table 2) from tubes with wear mark (Table 3).…”

This report summarizes structural integrity work performed for the U.S. NRC that predicts the rupture pressure and leak rate of flawed steam generator (SG) tubes. The work includes pressure testing of straight tubes with lab-induced outer diameter stress corrosion cracks (ODSCC). Existing models for predicting rupture pressure and leak rate of straight tubes with well-defined, rectangular, electro-discharge-machined (EDM) flaws were modified and used to predict the measured rupture pressures and leak rates from straight tubes with ODSCC. Models previously developed for EDM notches in straight tubes were modified for ODSCC by using the equivalent rectangular crack (ERC) method.

Eddy current testing is widely used for nondestructive evaluation of metallic structures in characterizing numerous types of defects occurring in various locations. It offers remarkable advantages over other nondestructive techniques because of its ease of implementation. This paper presents a technical review of Eddy current technique in various scope of defect detection. The first part presents Eddy current evaluation on various defects location and orientation such as steam generator tubes, stress crack corrosion, and fatigue cracks. The next section analyzes the use of pulsed Eddy current and pulsed Eddy current thermography as an alternative method for monitoring the growth of cracks with the aid of computational techniques for postsignal analysis.
