ABSTRACT:
The specification discloses a device (32) for raising peripheral fuel rods of a fuel assembly for inspection under submerged conditions in a nuclear reactor facility. The device (32) includes a frame comprising top and bottom plates (36, 38) interconnected by rods (40) with an intermediate plate (52) supported therein for vertical movement responsive to a cylinder (60). A yoke (64) is mounted for horizontal movement on the intermediate plate (52) responsive to another cylinder (66) to engage a fuel rod so that it can then be lifted by the first cylinder (60). Proper alignment relative to the peripheral rods of the fuel assembly is accomplished by means of pins (50) which are received in indexing holes (80) of a support plate (68) for the fuel assembly.
