ABSTRACT:
A method and apparatus are provided for the inspection of nuclear fuel rods to detect defects or failures in such rods. Assemblies of fuel rods are immersed in water and means are provided for causing a change in the relative pressures in the water and within the fuel rod such that material is expelled from the rod through any defects that may exist. Means are provided for detecting the emission of bubbles, or other material expelled from the rod, and for locating the position of the defective rod in the assembly. The method is also applicable to detection of contaminants in new fuel rods which may result in the development of defects in the rod.
