ABSTRACT
In January 2001, the X-probe Eddy Current array was qualified to Appendix H for a number of damage mechanisms. The X-Probe ECT array has now undergone 15 successful field trials in Westinghouse, CE, OTSG, and CANDU-type steam generators. This experience covers all areas of the tubes, including low-row U-bends. The field trials demonstrate that the X-Probe is an extremely fast and reliable probe for high-resolution detection and can advantageously replace rotating probes in a large number of inspections. Detection has been shown to be equivalent to that of current state-of-the-art rotating probes and no inspection transients are expected when switching to the X-Probe. This paper provides an overview of field experience accumulated so far and discusses the various issues raised during the trials. The qualification status of the probe is reviewed. An outline of recent and upcoming development surrounding this technology is also provided. Finally, the milestones remaining for full deployment of the X-Probe, namely analyst training and integration into current operations, are discussed.
