Eddy-current methods provide the best in-service inspection of steam generator tubing, but these techniques can produce ambiguity because of the many independent variables that affect the signals. The current development program has used mathematical models and has developed or modified computer programs to design optimum probes, instrumentation, and techniques for multifrequency, multiproperty examinations. Interactive calculations and experimental measurements have been made with the use of modular eddy-current instrumentation and a minicomputer. A field test was recently performed at Babcock and Wilcox, Lynchburg, Virginia, on tubing containing intergranular attack. The tubing was extracted from a Ginna steam generator for metallographic examination.
