    摘要: A process for improving packaging efficiency uses three dimensional, computer simulated models with various optimization algorithms to determine the optimal segmentation process and packaging configurations based on constraints including container limitations. The present invention is applied to a process for decontaminating, decommissioning (D&D), and remediating a nuclear facility involving the segmentation and packaging of contaminated items in waste containers in order to minimize the number of cuts, maximize packaging density, and reduce worker radiation exposure. A three-dimensional, computer simulated, facility model of the contaminated items are created. The contaminated items are differentiated. The optimal location, orientation and sequence of the segmentation and packaging of the contaminated items is determined using the simulated model, the algorithms, and various constraints including container limitations. The cut locations and orientations are transposed to the simulated model. The contaminated items are actually segmented and packaged. The segmentation and packaging may be simulated beforehand. In addition, the contaminated items may be cataloged and recorded.

    摘要: The irradiated component (1) comprises at least one tubular wall with its axis vertical and fastened inside a well (2) in a concrete structure (3). The connecting elements between the concrete structure (3) and the component (1) are destroyed, the component (1) is displaced in successive steps in the vertical direction along its axis on the inside of the well (2), and the wall of the component is cut, so as to obtain blocks (26) of irradiated material of the wall, at the upper level of the well (2) of the concrete structure (3) after each displacement of the component (1). The cut blocks (26) are disposed of for the purpose of elimination or storage. The displacement of the component can be obtained by a pull or push on its lower bottom.

    摘要: A metal cutting motor driven saw blade carried by a housing structure for anchoring inside the fuel storage cell forms part of apparatus that is used in method to reduce the volume of radiologically contaminated metal racks after use for storing nuclear fuel assemblies under water in a storage pool. The motor driven saw is supported by a linear bearing that can be displaced by an actuator laterally with respect to a housing structure which is provided with piston and cylinder assemblies on two adjacent side walls to serve as releasable anchors. The linear actuator presses the saw blade against a side wall of a fuel storage cell causing part of a blade segment to penetrate the side wall. Thereafter, a drive shaft supported by bearings in the housing structure is rotated to displace the motor driven saw about a radial path of travel for severing the remaining portions of the wall of the fuel cell. A segment of the fuel cell is freed from the welded construction of the storage racks whereupon the segment is subdivided by a crop saw, then crushed to reduce its requirement for storage space in a long term storage facility.

    摘要: The invention relates to a method and to apparatus for cutting irradiated fuel elements when in the horizontal position. A fuel element is placed on a support and presents a cross-section for cutting. The fuel element may be displaced along its longitudinal axis. In the immediate proximity of the cutting section, the fuel element is compressed by at least one side clamp, and between two cuts the side clamp(s) is/are unclamped, the fuel element is then advanced by a desired length, and the side clamp(s) is/are reclamped. The end pieces cut off by end piece cutters fall into a fixed end piece removal apparatus. The rods are cut up inside a cavity in such a manner as to confine the cut-off lengths therein, the cavity being provided with a bottom opening enabling the cut-off lengths to be removed and directed towards a fixed rod-removal apparatus. In a preferred embodiment, the end pieces are cut off against the front face of the carriage which carries the rod-cutting blade.

    摘要: A saddle with two cutting stations, i.e., front and rear openings, moves forward and backward horizontally within a chassis. The rear opening includes a cutting blade. The chassis includes a front counter blade. A magazine holds a tube bundle and includes a rear face clamp and rear counter blade. In a first cutting operation, skirting at the base of the tube bundle is placed in the front opening and is cut by first moving the saddle rearward against the rear face clamp and rear counter blade, and then frontward against the front counter-blade. In a second cutting operation, the tube bundle is placed in the rear opening. As the saddle is moved frontward, the cutting blade in the rear opening cooperates with the front counter-blade on the chassis to cut the tubes. This second cutting operation is continued until the tubes are cut.
