摘要： The tie rod repair apparatus includes a tie rod secured at its upper end to the shroud flange at the top of the shroud. The lower end of the tie rod passes through an opening in the shroud support plate without imposing a load on the plate. The lower end of the tie rod is anchored to the lower end of the core shroud support cylinder such that the compressive load path exerted by the tie rod to restrain the cracked shroud passes directly through the shroud support cylinder and the assembly of shroud cylinders bypassing the shroud support plate.

摘要： A method for applying a lateral support load to a jet pump slip joint. The method includes positioning an ovalization device around the diffuser and actuating the ovalization device to apply a predetermined load to the slip joint which creates an oval deformation of the diffuser. The force applied by the ovalization device creates a plastic strain in the diffuser wall which permits the diffuser to maintain an oval shape, and an elastic strain in the wall of the inlet mixer. The elastic deflection of the inlet mixer which is restrained from its original shape applies a lateral preload force to the diffuser at the area where the diffuser has a reduced diameter due to the oval deformation. This lateral preload force maintains a rigid contact between the inlet mixer and the diffuser collar to prevent oscillating motion and suppress FIV.
摘要翻译：一种用于将横向支撑载荷施加到喷射泵滑动接头的方法。该方法包括将椭圆形装置定位在扩散器周围并致动椭圆形装置以向滑动接头施加预定的载荷，从而产生扩散器的椭圆形变形。由椭圆形装置施加的力在扩散壁中产生塑性应变，其允许扩散器保持椭圆形状，并且在入口混合器的壁中产生弹性应变。入口混合器的弹性挠曲受限于其原始形状，在扩散器由于椭圆形变形而具有减小的直径的区域向扩散器施加横向预载荷力。该侧向预紧力保持入口混合器和扩散器套环之间的刚性接触，以防止振动运动并抑制FIV。

摘要： A remotely installable piping support device includes a pair of mating tapered wedge segments extending from lever arms connected with a spiral wound spring. The spring is machined integrally with the left lever arm and has a projecting center square drive hub with an internal mounting thread. The right lever arm has an internal square drive which mates with the drive hub. A bolt engages the drive hub and secures the lever arms together. The spring preload on the wedge acting across the shallow angled wedge surfaces maintains rigid contact between jet pump components and takes up the clearance from wear during operation.

摘要： An apparatus for repairing a shroud in which one or more seam welds are cracked. The repair involves the attachment of a splice bracket to the shroud so that the bracket bridges the cracked weld seam and is applicable to both vertical and horizontal weld seams. The bracket is intended to structurally replace the shroud seam weld which is cracked. Multiple splice brackets can be placed along the length of a crack. Each splice bracket is attached to the shroud by a plurality of tapered fastener assemblies. Each tapered fastener assembly includes a first fastener element having a threaded surface and a conical surface coaxial with the threaded surface; a slotted sleeve having an internal surface which matches the conical surface of the first fastener element and an external surface which matches a circular cylindrical surface, and a flange which extends radially outward beyond the external surface; and a second fastener element having a threaded surface threadably engaged with the threaded surface of the first fastener element. The sleeve fits inside aligned holes in the splice bracket and shroud.
