An eddy current probe uses magnetic gap. The probe has a small size; and coil number in the probe is reduced. Hence, the probe can move easily inside and outside a tube and detect an end of the tube as close as possible.

An ultrasonic wave passes different fuels of different concentrations with different velocities. The present invention provides a detecting and controlling device where, by a non-touching method, a velocity for an ultrasonic wave in a first fuel with a first fuel concentration is measured. The velocity obtained is taken for a comparison with another velocity for the same ultrasonic wave in a fuel with a default fuel concentration so that the first fuel concentration of the fuel can be under controlled.

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.
