摘要： A portable and collapsible radiation shielding device is provided for the protection of personnel and equipment from ionizing radiation. The shield has a plurality of horizontally elongated slats of radiation shielding material, such as lead wool, hung from a plurality of horizontally spaced apart chains at spaced intervals along the length of the chains. The slats are connected to the chains near their top edges so that when they are in their raised state the slats are suspended from the chains and arranged in an overlapping manner, like shingles, and when collapsed arrange themselves neatly side by side in a stack. The device also has a container adapted to receive the shield in its collapsed state, and a hoist and mast for raising and lowering the shield into and out of the container. The container further has wheels for facilitating moving the device to the desired location, and an outrigger for providing stability to the shield when raised. The mast is dissassemblable so that it can be stored within the container along with the shield when not in use. The container may also have an opening at an end to facilitate removal of the radiation shield from the container when it is supported by means other than the mast.

摘要： An apparatus for consolidating spent fuel rods from spent fuel assemblies includes a container with a bottom and front, back, and side walls. The container has a plurality of flutes positioned adjacent to the front wall, and the plurality of flutes defines a plurality of channels. The apparatus also includes a plurality of springs, which are mounted on a support. The springs bear against the flutes and the channels when no fuel rods have been inserted into the container and the support is located proximate the front wall. The springs assist in guiding a fuel rod into a preselected location in the container; the springs are capable of maintaining the fuel rod in the preselected location. Preferably, each spring is a resilient finger that extends outwardly from the support toward the front wall. The support may be a movable sheet. The apparatus advantageously includes a device for moving the support. Such a device may automatically position the support in response to control signals.

摘要： A system for consolidating spent fuel rods from spent fuel assemblies includes an operator and control station, a fuel rod transfer tool with a gripper assembly, indexing devices, and a fuel consolidation station. The fuel rod transfer tool and gripper assembly grips a fuel rod and withdraws it from a fuel bundle until it is clear of the bundle. The tool, with the fuel rod drawn up inside it, is moved to another location where it is desired to place the fuel rod; the tool inserts the rod, and the gripper releases it. The fuel consolidation station has a frame that holds two fuel assemblies and a consolidation container. The bottom of the frame rests on the floor of the fuel pool. The top of the frame supports the indexing devices. An indexing device is provided for each of the fuel assemblies and the consolidation container. An indexing device for a fuel asembly is capable of guiding the gripper assembly to a position above a preselected rod in the associated fuel assembly, while the indexing device for the consolidation container is capable of guiding the gripper assembly, which may be holding a rod, to a position above a preselected location in the consolidation container. Preferably, each indexing device has an indexing head that is slidably mounted on a pair of rails, and these pairs of rails are slidably mounted on a further pair of rails. The further pair of rails runs transversely to the former pairs of rails, thus permitting each indexing head to be moved in two perpendicular directions.
