ABSTRACT:
A modified inspection apparatus for inspecting nuclear fuel pellets for surface defects includes a pellet guide chute assembly extending through an ultrasonic inspection chamber. The guide chute assembly has a support substrate and a pair of elongated plates attached on respective upper adjacent sides of the substrate. The substrate is composed of a pair of elongated wall sections rigidly attached together to have a V-shaped configuration in cross section. The plates are adjustably attached on the substrate wall sections for supporting a nuclear fuel pellet between and on adjacent longitudinal portions of the plates located in the inspection chamber. The plates have respective slots and cutout regions underlying the pellet at the adjacent longitudinal portions of the plates so as to expose portions of the support substrate wall sections also underlying the pellet such that acoustical energy can be propagated to and from bottom and side portions of the pellet via reflection of the acoustical energy from the exposed wall section portion. Also, an acoustical energy reflecting cover is disposed over the guide chute assembly at the inspection chamber. Further, a pellet position sensing arrangement and a transducer array for transmitting and receiving acoustical energy are included in the modified inspection apparatus.
