Abstract

This report provides an assessment of various advanced nondestructive evaluation (NDE) techniques for inservice inspection of steam generator tubing. Selected results are presented on the application of data processing and visualization techniques; data analysis, including depth sizing and the development of correlations between eddy current signals and tube failure pressure by multivariate regression and neural networks; inspection of sleeved tubes; applications of ultrasonic NDE; and related work on emerging NDE technology.
