Abstract
A tool for inspecting a cell formed by grid beams of a top guide structure in a nuclear reactor is provided. The tool includes a camera; a support structure coupled to the camera for contacting at least one of the grid beams to support the camera within the cell; and at least one actuator moving the camera with respect to the support structure and along one of the grid beams, the at least one actuator coupling the camera to the support structure. A method for inspecting a cell formed by grid beams of a top guide structure in a nuclear reactor is also provided.

A tool for inspecting a cell formed by grid beams of a top guide structure in a nuclear reactor comprising:
- a camera;
- a support structure coupled to the camera for contacting at least one of the grid beams to support the camera within the cell;
- and
- at least one actuator moving the camera with respect to the support structure and along one of the grid beams, the at least one actuator coupling the camera to the support structure.
A method for inspecting a cell formed by grid beams of a top guide structure in a nuclear reactor comprising:
- providing a tool including a camera within the cell so that the tool contacts at least one of the grid beams and sits within the cell;
- and
- inspecting a first grid beam of the grid beams while the tool sits within the cell by moving the camera along the first of the grid beams.
