摘要： A fuel assembly, particularly advantageous for use with a BWR, wherein the fuel bundle is adapted to be inserted into an envelope formed from a flow channel and a lower nozzle assembly. The fuel bundle is essentially axially symmetrical having identical top and bottom tie plates. Within the fuel bundle, alternate fission gas plenums are disposed at the top and bottom of the bundle respectively.During the refueling operation, the fuel bundle is removed from the reactor core, axially inverted and reinserted into the core for continued burn up. The invention takes advantage of the reactivity increase possible in a BWR when a partially burned fuel bundle is inverted.

摘要： A novel and improved drawing desk is provided which can be folded between a storage position and a drawing position. The desk has a center leg which raises from a first end located on the floor to a second end which is pivotally attached to an end leg. By pivotally attaching the center and end legs, the longitudinal axes of the center leg and end leg can be positioned so that they are substantially parallel in the storage position and substantially transverse in the drawing position. An easel is pivotally attached to the center leg for receiving a removable drawing board. A seat assembly, pivotally attached to the center leg, has a protruding seat arm adapted to engage a seat slot disposed in the center leg and a device for adjusting the position of the seat in order to accommodate users of different sizes. In the preferred embodiment, the adjusting device comprises the seat leg having a bottom end which is adapted to engage a plurality of openings disposed along the center leg. By aligning the longitudinal axes of the seat, the seat leg, the end leg, easel and the center leg in the storage position, the drawing desk is relatively compact so that numerous desks may be stored in a small area.

摘要： A reusable fastener device includes an attachment nut and a retainer housing mounted to the adapter plate of the fuel assembly top nozzle and removable with the top nozzle upon reconstitution of the fuel assembly. The attachment nut has a central tubular stem and upper and lower flanges connected to and extending radially outwardly from opposite ends of the stem. The stem is internally threaded for mating with the threaded upper end plug extension of the strucutural member. The upper flange of the nut has a conical-shaped lower surface and a periphery adapted for engagement in order to rotate the nut for threading onto and unthreading from the structural member extension between fastened and unfastened positions. The lower flange of the nut is in the form of a plurality of radial segments extending outwardly from the stem and angularly spaced from one another so as to define a plurality of cutouts therebetween which alternate with the segments. The retainer housing has a tubular hollow body and a plurality of upper sectors and lower tabs connected to and extending respectively radially inwardly and outwardly from opposite ends of the tubular body. The upper sectors are angularly spaced from one another so as to define a plurality of openings sized to receive the radial segments of the nut therethrough. Also, the upper sectors extend radially inwardly from the tubular body so as to define a central opening sized to receive the central stem of the nut and to define an interrupted conical-shaped upper surface surrounding the central opening which matches the conical-shaped lower surface on the upper flange of the nut. The lower tabs rest upon and are rigidly connected to the top nozzle adapter plate so as to align the central opening of the retainer housing with the hole through the adapter plate and dispose the upper sectors in a location spaced from the adapter plate at which their interrupted conical-shaped upper surface will be contacted by the conical-shaped lower surface of the upper flange of the nut when the central stem thereof is threaded onto the upper end extension of the structural member to the fastened position. The upper sectors are yieldably deflectible upon being contacted by the upper flange of the nut such that inner edges of the upper sectors engage the central stem of the nut so as to rotationally lock the lower flange of the nut to the adapter plate when the nut is rotated to its fastened position. Finally, the retainer housing also includes auxiliary tabs attached to the upper sectors and being bendable between open and closed positions for respectively allowing and preventing passage of the lower segments of the nut through the openings defined between the upper sectors of the retainer housing.

摘要： A fuel assembly for use at non-control rod locations of a nuclear reactor core includes top and bottom nozzles and longitudinal structural members extending between and attached to the nozzles for forming an integral unitary structure. One or more of the structural members includes an elongated hollow cladding tube extending between the top and bottom nozzles and end plugs secured to opposite ends of the tube for hermetically sealing and attaching the tube to the top and bottom nozzles. The improvements in the structural member relate to features for reducing fuel assembly bow. Such features relate to a quantity of thermal or irradiation-induced creep resistant material and pretensioning means positioned within the tube. The creep resistant material is a ceramic material in stacked pellet form and coated with a burnable adsorber material. The pretensioning means applies a predetermined compressive load to the ceramic pellet stack and reacts the load so as to preload the tube in a state of pretension having a magnitude sufficient to substantially counteract an axial load typically transmitted through the unitary structure of the fuel assembly and thereby greatly reduce the compressive stress in the structural member tube. There are two embodiments of the pretensioning means. In one embodiment, it is an elongated bellows type device positioned within the tube between the ceramic pellet stack and one of the tube ends, with the interior of the bellows type device being pressurized to create a predetermined axial force therein which places the ceramic pellet stack in compression and the tube in the state of pretension. In the other embodiment, it is an arrangement of belleville springs positioned within the tube between the ceramic pellet stack and one of the tube ends and stacked both in series and in parallel.

摘要： A nuclear reactor in which control rods are inserted in the thimbles of only certain of the fuel assemblies (which may be called controlled assemblies) in the core and the remainder of the assemblies (which may be called non-controlled assemblies) are provided with hollow structural members containing burnable poison which form these non-controlled assemblies into integrated units. The hollow structural members are formed with end plugs welded to the lower end and are open at the top. The end plug of each member is secured to the bottom nozzle of the non-controlled fuel assembly. A skeleton is formed of the bottom nozzle, the structural members secured to it and a plurality of grids spaced along the structural members. A bulge tool is then inserted in each hollow member and it is on each side of each grid. Neutron absorbers are then inserted in each hollow member and an upper end plug is welded to it. The fuel rods are then inserted in the assembly and the upper end plugs are secured to the top nozzle.Typically, there are 24 thimbles in a controlled assembly but not all thimble locations in a non-controlled assembly contain neutron-absorber structural members. Typically, there are eight structural members in a non-controlled assembly. In the other positions there are fuel rods. In reactors where there are water displacement control rods which extend over several assemblies, the so-called non-controlled assemblies may have the necessary thimbles for the water displacement rods.

摘要： A trap for catching debris carried by coolant flowing from the bottom nozzle of a fuel assembly to the bottom or lowermost one of the grids of the assembly which support the fuel rods in an organized array therein includes a structure disposed between the bottom nozzle and the bottom grid and generally aligned with the lower end plugs of the fuel rods. The structure forms a multiplicity of hollow cells each being open at opposite ends and defining a central cavity which receives one of the fuel rod lower end plugs while providing for passage of coolant flow therethrough from the bottom nozzle to the bottom grid. Also, the trap includes means in the form of dimples defined in each of the cells for catching debris carried into the cells by the coolant flowing therethrough. The dimples are formed from the wall portions defining the cells and extend into the cavities of the cells. Each dimple has a configuration generally arched outwardly from the wall portion which is oriented in alignment with the direction of coolant flow through the cell. The distance between those dimples formed on oppositely-disposed ones of the wall portions is slightly greater than the diameter of the fuel rod lower end plug disposed in the cavity of each cell. Additionally, the debris trap further includes structure support means in the form of a plurality of hanger straps attached at their lower ends to the structure adjacent the corners thereof and at their upper ends to the bottom grid so as to locate the structure in the spaced relationship below the bottom grid and support the structure adjacent the corners thereof from the bottom grid.

摘要： A device for unfastening and lifting a top nozzle subassembly from the guide thimbles of a reconstitutable fuel assembly includes hollow gripper tubes having open lower ends, spaced yokes mounting the gripper tubes, pull rods disposed in the gripper tubes, end plugs attached to lower ends of the pull rods and disposed at the open lower ends of the gripper tubes, stop plugs stationarily disposed in the gripper tubes spaced above their open lower ends, elastomer blocks disposed in the gripper tubes between the end and stop plugs, and inner tubes disposed within the gripper tubes about the elastomer blocks. Lower end portions of the gripper tubes are capable of insertion into sleeves of the top nozzle subassembly to positions therein located adjacent to threaded lower ends of the sleeves. The pull rods are disposed within the gripper tubes for axial movement upwardly and downwardly within the tubes, with the end plugs being extendible into and from the gripper tube open lower ends upon such movement of the pull rods. In such arrangement, movement of each pull rod upwardly displaces the end plug thereon toward the stop plug and causes diametric expansion of the block which, in turn, causes diametric expansion of the gripper tube into engagement with the sleeve adjacent to the threaded lower end thereof, whereas movement of the pull rod downwardly displaces the end plug thereon away from the stop plug and allows diametric contraction of the block which, in turn, allows diametric contraction of the gripper tube out of engagement with the sleeve. Each gripper tube lower end portion contains spaced axial slots for facilitating diametric expansion of the gripper tube which enables subsequent unthreading of the sleeve from the guide thimble. Also, the inner tube about the elastomer block is axially slotted and oriented such that its slots are circumferentially displaced from those of the gripper tube so as to prevent the elastomer block from extruding outwardly through the slots of the gripper tube when the block is diametrically expanded.

摘要： A nuclear reactor fuel rod includes a fuel tube and an improved end plug assembly having a pair of hollow end plugs which seal opposite ends of the fuel tube. Each end plug has an outer body portion with an outside diameter substantially the same as the outside diameter of the fuel tube and an inner body portion of reduced diameter inserted into an end of the tube. Each plug has a cavity defined therein which increases the space within the rod for fission gas expansion. An outer region of the cavity within the outer body portion of the end plug is undercut relative to an inner region of the cavity within the inner body portion of the plug. One of the end plugs also has an insert fitted into its inner body portion which prevents fuel chips from falling into the cavity of the end plug. A slot is formed axially in a side wall of the insert which allows communication of gas from the tube into the cavity of the end plug.

摘要： A boiling water nuclear power reactor includes an improved control rod associated with each of its clusters of fuel assemblies. The control rod has an elongated central stem defining a longitudinally extending internal central gas plenum and a plurality of blades orthogonally arranged in pairs to provide a cruciform configuration in which the blades connect to and extend radially outward from the central stem. Each blade incorporates a series of internal cavities arranged in columns and rows across the length and width of the blade, and a neutron absorbing pellet is disposed in each cavity. The cavities communicate with the central plenum so that any gases generated by irradiation of the pellets can expand into the plenum. The cavities and pellets are arranged to form a longer, constant worth section in a body portion of each blade and a shorter, reduced worth section in an end tip portion of each blade. The end tip portion leads insertion of the blade body within the space between adjacent fuel assemblies when the control rod is moved into the fuel assemblies to control the reactive power thereof.
