Abstract
A mechanism for testing fuel tubes in nuclear fuel bundles includes a carriage, carrying an elongated probe, and a grooved plate. The grooves are parallel to the probe and are spaced by the same distances as rows of tubes in the fuel bundle. They are connected at at least one end. A pin on the carriage fits in the grooves. A hydraulic cylinder reciprocates the carriage longitudinally of the grooves and a pneumatic cylinder urges it laterally, so that the pin moves from groove to groove at the end of each stroke.
