Abstract
The present invention relates to a nondestructive method or inspecting defects of the cladding of a nuclear fuel rod, which is featured by a wave emitter obliquely discharging an inspection wave to an inspected tube and a receiver arranged at a side of the inspected tube with respect to the wave emitter. If liquid is accumulated inside the tube, the incident inspection wave will be refracted so that the receiver can receive the refracted inspection wave at a specific location. The method can determine whether liquid is accumulated inside the tube and further is able to detect the level of the liquid.
