    摘要: A steam generator tube support structure having three sets of mutually parallel strips each set extending in a different direction oriented sixty degrees from the other two. One set of strips is slotted at both edges. The other two sets of strips are slotted on one edge. The strips engage to form hexagonal cells for supporting and aligning a triangular array of tubes. Dimples in the strips provide point tube support.

    摘要: A typical embodiment of this invention provides a hydraulic mechanism for alleviating the effect of seismic forces and other stresses that are applied to a fuel assembly in a nuclear reactor. Illustratively, hollow guide posts protrude into a fuel assembly end fitting grid from biased spring pads. Plungers that move with the spring pads plug one end of each of the respective guide posts. Plates on the end fitting grid that have individual holes for fluid discharge partially plug the other ends of the respective guide posts, thereby providing a hydraulic means for absorbing the longitudinal component of seismic shocks and other anticipated forces.

    摘要: A typical embodiment of the invention provides a nuclear fuel assembly lock structure for control rod guide tubes. Illustratively, a sleeve telescopes over an end portion of a control rod guide tube which bears against an internal shoulder of the tube. The upper end of the sleeve protrudes beyond the control rod guide tube spider and is locked in place by means of a resilient cellular lattice or lock that is seated in a mating groove in the outer surface of the sleeve. A special tool is provided for disengaging the entire lock structure, washer, spider, spring and grill from the end of the fuel assembly in order to enable these components to be removed in an assembled state and subsequently replaced on the fuel assembly after inspection and repair.

    摘要: A typical embodiment of the invention provides a means for restraining the fuel elements within a nuclear reactor core from movement during reactor operation. Illustratively, within one of the fuel element end fittings a rectangular grid of torsion bars is positioned with the ends of each of the bars anchored in opposing parallel sides of the end fitting. Individual torsion arms fastened to the midportion of each of the respective torsion bars protrude above the end fitting to bear against the adjacent grid pads and thereby restrain motion in the direction of coolant flow. In the opposite fuel element end fitting a tube that extends through the length of the fuel element is connected to the center of a convex spring. The two ends of the spring are hinged to respective locking bars that are cammed to move in a direction that is transverse to the axis of the tube. As the fuel element moves in the direction of coolant flow, the tube presses the convex spring flat. The flattening spring, in turn, drives the locking bars into engagement with mating latches on the adjacent support grid to prevent further movement of the fuel element.

    摘要: A typical embodiment of the invention has an array of sockets that are welded to the intersections of the plates that form the upper and lower end fittings of a nuclear reactor fuel element. The sockets, which are generally cylindrical in shape, are oriented in directions that enable the longitudinal axes of the sockets to align with the longitudinal axes of the fuel rods that are received in the respective sockets. Detents impressed in the surfaces of the sockets engage mating grooves that are formed in the ends of the fuel rods to provide for the structural integrity of the fuel element.

    摘要: A typical embodiment of the invention provides an efficient aid in positioning fuel elements in a nuclear reactor core. The corner edges of the peripheral band that binds the fuel element grid structure together, as well as the ends of the individual grid plates that protrude beyond the last marginal rows of fuel rods in each of the fuel elements are chamfered or bevelled. Thus, when fuel elements are being inserted, relocated or withdrawn from a reactor core the sloping edges of the grid structures in adjacent elements slide past without locking together or otherwise undesirably engaging each other.
