A system for manipulating radioactive fuel rods within a nuclear fuel assembly.

摘要

A system constructed of three tools for manipulating fuel rods with a nuclear fuel assembly is disclosed. The individual tools are adapted for displacing fuel rods upwardly and downwardly along their longitudinal axes and for rotating same 3600 without having to remove the fuel rods from their location within a nuclear fuel assembly. The individual tools are operative on-site and are controlled from a remote location while the nuclear fuel assembly is maintained underwater in a spent fuel pool. By manipulating the fuel rods, those rod areas which are not open for visual inspection such as within grids may be inspected for defects and the like.
