ABSTRACT:
A pressure vessel penetration sidewall adjacent a tube installed in the penetration by a clearance fit is inspected by passing an eddy current probe having a pair of circumferential coils through the tube. Eddy currents are induced in the pressure vessel as the probe passes through the penetration tube and degradation of the pressure vessel adjacent the clearance is determined based upon the eddy currents induced in the pressure vessel by the probe.
