Non-contact laser ultrasound (LU) method is a potential
tool for structural health evaluation in power plants. In
this study a LU surface wave method was employed to
determine the oxide layer thickness in zircaloy tubes
used as cladding of fuel rods in nuclear reactors.
Ultrasound excitation was done with a pulsed laser
whereas a laser doppler interferometer was used to
remotely receive the propagating ultrasonic signals. To
show the method's capability results from a 8 µm
zirconium oxide layer measurement are presented.
