APPARATUS FOR THE IN-SITU INSPECTION OF TUBES WHILE SUBMERGED IN A LIQUID PARTICULARLY OF A NUCLEAR REACTOR STEAM GENERATOR

摘要

Apparatus for the in situ inspection of tubes which are submerged in a liquid such as the primary coolant of a nuclear reactor, wherein a sensor is withdrawn from a tube by a cable, including means for removing the liquid from and drying the cable and returning the liquid to the tubes thus preventing the spread of deleterious liquids to otherwise benign environments and the fouling of the drive mechanism used to control cable movements.
