摘要： A rod arraying system for nuclear fuel rods or burnable poison rods. A support structure positions a consolidation canister vertically to receive the rods. A rod loading pattern provides a gap between rods to allow projections to hold each rod in position. One or more rod arraying devices positioned vertically along and inclined toward the canister provide a triangular pitch loading configuration. A guide assembly slidably mounted on the mounting base of the rod arraying device has two guide plates with scalloped edges. The guide plates are offset relative to each other with one being cycled back and forth by an air cylinder to allow individual loading of fuel rods one row at a time. The inclined weight of the guide plates keeps them in position against the rods to prevent unwanted shifting of rods during the loading operation.

摘要： In order to transfer a bundle of rods of or from a nuclear fuel assembly into a storage case, the bundle is placed in a waiting position above a cassette provided with recesses. The rods are then introduced into the recesses by lowering them by gravity. When the cassette is full, it is brought into the extension of the case by interposing a transformation member. By simultaneously exerting a thrust on all the rods, the latter are compactly transferred into the case.

摘要： A fuel element bundle cutter that has horizontal rod bundle feed. A portionf the radioactive dust that is produced when a rod bundle is cut is picked up by scavenging air and is withdrawn with the latter via the chute for the cut-off rod pieces. The bottom of the lower part of the cutter housing, between the housing wall that faces the rod bundle feed and the side walls of the housing, is embodied as a grating, on the bottom side of which is disposed a base plate to which is connected a withdrawal mechanism that includes at least one collecting funnel and withdrawal channel for the remainder of the radioactive dust, which is conveyed by a portion of the scavenging air from the cutter housing. Each withdrawal channel communicates with the chute for the cut-off rod pieces.

摘要： Horizontal fuel element bundle shears have a stepped blade and a horizontalagazine for accommodating an undismantled uclear reactor fuel element which is to be cut up. In the fuel element bundle shears, the nuclear reactor fuel element, for the cutting operation to be performed, is pushed with a stepwise movement through a magazine opening in front of which the stepped blade is displaceable in a direction perpendicular to the longitudinal axis of the fuel element. Each portion of the stepped blade has a cutting edge. In order to achieve a lower rate of wear of the stepped blade while at the same time obtaining a good cut and a low cutting force, the stepped blade has two cutting edges which are separated from each other by a step, thereby forming two blade portions which are in superposed relationship with each other. The lower blade portion is set back with its cutting edge relative to the cutting edge of the upper blade portion by a step distance which corresponds at least to the width of the precompacted fuel element bundle. The upper cutting edge is higher or longer than the lower cutting edge. Because of this configuration, the two blade portions, which are separated by a step, do not come into engagement with the bundle simultaneously but instead engage the bundle sequentially.

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 360.degree. without having to remove the fuel rods from their location within a nuclear fuel assembly. The individual tools are operative on-site from a remote location while the nuclear fuel assembly is maintained underwater in a spent fuel pool. By manipulating the fuel rods, those areas previously hidden from visual inspection such as within grids may be inspected for defects and the like.

摘要： In a reconstitutable fuel assembly, a top nozzle attaching structure for mounting the top nozzle adapter plate in releasable locking engagement upon the guide thimble upper end portions includes several improved features. First, each locking tube is mounted within the guide thimble upper end portion for movement between an upper locking position wherein the adapter plate and guide thimble upper end portion are maintained in locking engagement and a lower unlocking position wherein the adapter plate is releasable from the guide thimble upper end portion. Also, cooperating means are defined on the locking tube and the guide thimble for retaining the locking tube at either of its upper or lower positions. The guide thimble cooperating means includes a pair of upper and lower circumferential bulges defined on the guide thimble upper end portion below the adapter plate. The bulges are axially spaced from one another such that the upper bulge is located to retain the locking tube at its upper locking position and the lower bulge is located to retain the locking tube at its lower unlocking position. The locking tube cooperating means includes a circumferential bulge defined on a lower portion of the locking tube which is seatable in either of the bulges of the guide thimble and several slots defined in the locking tube which extend upward along its lower portion from a lower edge thereof. The slots allow radial compression and expansion of the lower portion of the locking tube for facilitating its movement between and positioning at its upper and lower positions.

摘要： A fixture for inserting and removing locking tubes into and from locking positions in a top nozzle includes a lower traveling plate and an upper traveling plate disposed above the lower plate. The lower plate has hollow flexure tubes attached to and projecting downwardly therefrom. Each flexure tube has an axially segmented sleeve portion which terminates in a lower segmented rim, with the rim being expandable to a first outside diameter greater than an inside diameter of the locking tube and collapsible to a second outside diameter less than the inside diameter of the locking tube. The upper plate has actuating rods attached to and projecting downwardly therefrom through the flexure tubes. Each actuating rod has a shaft portion which terminates in a lower enlarged nose disposed below the segmented rim of one flexure tube such that movement of the plates away from one another forcibly inserts each enlarged nose into one segmented rim sufficiently to expand the same to its first outside diameter size wherein the segmented rim will engage the lower end of each locking tube, whereas movement of the plates toward one another withdraws each enlarged nose from each segmented rim sufficiently to allow contraction of the same to its second outside diameter size wherein the segmented rim will fit through the locking tube.
