The eddy current examinations were performed utilizing various eddy current probes.

All examination techniques utilized were qualified for detection of the relevant degradation mechanisms. This qualification is in accordance with the EPRI SG Examination Guidelines, Revision 8. The applicable Examination Technique Specification Sheets (ETSS) are listed for reference only. Site-specific examination technique sheets are developed prior to each steam generator inspection in accordance with Appendix H or I (as applicable) of the EPRI SG Examination Guidelines, Revision 8.
