Abstract: Methods and apparatus for examining a nuclear reactor shroud are described. In one embodiment the inspection apparatus includes a scanner subassembly movably coupled to a base subassembly. The base subassembly includes a linear bearing attached to a first end of the base assembly and positioned to extend from the top to the bottom of the base assembly. At least one jacking cylinder is coupled to the second end of the base assembly. The scanner subassembly includes a mounting member movably coupled to the linear bearing, a rotating member pivotally coupled to the mounting member, an elongate radial bearing coupled to the mounting member, and a carriage assembly movably coupled to the radial bearing. The carriage assembly includes a scanner arm, and the scanner arm includes an inspection probe coupled to each end of the arm. The scanner arm is configured to be parallel to the radial bearing.
