The ability of eddy current inspection to detect and size flaws in Inconel 600 steam generator tubing at the tube sheet was studied. Single frequency absolute, single frequency differential, and multi-frequency differential eddy current tests were conducted on small, medium, and large volume defects placed into a simulated tube sheet. Position of each defect was varied with respect to the surface of the tube sheet. Results are presented on detectability and sizing of the defects versus measurement method, location of the defect relative to the tube sheet surface, and defect volume
