摘要： A thimble grip fuel assembly handling tool (20) for transporting fully loaded fuel assemblies (52) is disclosed. The tool (20) comprises an elongated mast (23) slidingly disposed within an elongated cylinder (113), the cylinder being of a length less than the mast (23) such that the tool defines a mast fill-up position (126) and a mast full-down position (128). A cage (110) assembly acts to protect the gripping means (32) when the tool is transported in the mast full-up position (126). The gripping means (32) is comprised of a plurality of gripping members (49) which grip the inside diameter of control rod guide thimbles (50). The load path is distributed in the tool such that when the fuel assembly (52) secured to the gripping means (32) is raised, the weight of the fully loaded fuel assembly (52) acts to increase the gripping force on the fuel assembly. A number of indicators on the tool act to indicate to an operator: when the tool is in the mast full-down position; when the gripping members (49) have been fully actuated; and if there is any slipping of the gripping members within the fuel assemblies. The tool also includes a secondary gripping mechanism which engages the top nozzle of the fuel assembly.

摘要： A nuclear reactor such as a pressurized water reactor has an integrated head package providing structural support and increasing shielding leading toward the vessel head. A reactor vessel head engages the reactor vessel, and a control rod guide mechanism over the vessel head raises and lowers control rods in certain of the thimble tubes, traversing penetrations in the reactor vessel head, and being coupled to the control rods. An instrumentation tube structure includes instrumentation tubes with sensors movable into certain thimble tubes disposed in the fuel assemblies. Couplings for the sensors also traverse penetrations in the reactor vessel head. A shroud is attached over the reactor vessel head and encloses the control rod guide mechanism and at least a portion of the instrumentation tubes when retracted. The shroud forms a structural element of sufficient strength to support the vessel head, the control rod guide mechanism and the instrumentation tube structure, and includes radiation shielding material for limiting passage of radiation from retracted instrumentation tubes. The shroud is thicker at the bottom adjacent the vessel head, where the more irradiated lower ends of retracted sensors reside. The vessel head, shroud and contents thus can be removed from the reactor as a unit and rested safely and securely on a support.

摘要： A guide pin assembly for aligning the upper hold down plate of the top nozzle of a fuel assembly with the upper core plate of a pressurized water nuclear reactor includes a guide pin, a nut and a locking cup. The guide pin includes a nose, a threaded portion, a shaft, and an end. The radial alignment section of the shaft has a diameter that is approximately the diameter of a bore in the upper core plate of a nuclear reactor. The lower section of the shaft has a diameter less than that of the radial alignment section. The end includes a top having a diameter greater than that of the diameter of the bore in the upper core plate. The guide pin is insertable within a bore in the upper hold down plate of the top nozzle of the fuel assembly and through the bore in the upper core plate so that the nose and at least a portion of the threaded portion of the guide pin protrude above the upper core plate. The nut is adapted to be threaded onto the threaded outer surface of the threaded portion of the guide pin. The locking cup is securable about the nut and is adapted to engage engagement apparatus on the nose of the guide pin when the nut has been tightened onto the threaded portion of the guide pin so that the bottom of the nut abuts the upper surface of the upper core plate.

摘要： A refueling machine (10, 100) within a nuclear reactor facility includes an outer stationary mast (12, 112) upon which are mounted a plurality of light sources (28, 128), inclined mirrors (36, 136), and television cameras (24, 124) for scanning a fuel assembly (32) for the existence of any defects or damage as the fuel assembly (32) is being withdrawn from the reactor core into the stationary mast (12, 112). In a first embodiment, the light sources (28), mirrors (36), and cameras (24) are mounted upon a sleeve (14) clamped about the lower end of the stationary mast (12), while in a second embodiment, the light sources (128), mirrors (136), and cameras (124) are mounted upon a basket-type framework (178) which is suspendingly supported upon the stationary mast (112) by support cables (158). A fixture (176) can support the framework (178) in an off-the-mast mode so as to permit remote-controlled maintenance or repair of the light sources ( 128), mirrors (136), or cameras (124). The mirrors (36, 136) may be eliminated and the light sources re-oriented so as to illuminate the reactor core and thereby facilitate the insertion of a fuel assembly (32) within the reactor core. Television monitors and tape recorder apparatus (168) are disposed upon the refueling machine trolley (150) for remote viewing of the scanned fuel assembly or viewing of the reactor core during an insertion mode of the refueling operation.

摘要： A method of crimping a locking cap secured to the nut of a new split-pin assembly to the new split-pin to preclude turning of the nut and pin relative to each other. The method is practiced with apparatus including a crimping mechanism including crimping jaws having crimping pins face-to-face near one end. The jaws have external cam surfaces. The crimping pins are retracted and brought into crimping engagement with the cap to be crimped by cam followers which traverse the cam surfaces when actuated hydraulically through a C-frame connected to the cam followers. The crimping mechanism is mounted on a support which is moveable by a hydraulic cylinder between a retracted setting, where it is latched generally vertically, and an operating setting where it is positioned generally horizontally. The support is pivoted vertically from the retracted position to an intermediate horizontal position during a first part of the stroke of the piston rod of the cylinder and is pivoted horizontally in position to perform a crimping operation during the last part of the stroke of the piston rod.

摘要： Apparatus is disclosed for handling radioactive fuel assembly during transfer operations. The radioactive fuel assembly is drawn up into a shielding sleeve which substantially reduces the level of radioactivity immediately surrounding the sleeve thereby permitting direct acess by operating personnel. The lifting assembly which draws the fuel assembly up within the shielding sleeve is mounted to and forms an integral part of the handling apparatus. The shielding sleeve accompanies the fuel assembly during all of the transfer operations.

摘要： Refueling apparatus for a nuclear reactor including a bridge and a trolley. The bridge is moveable in tracks along the containment of the pit in which the reactor is immersed in water and the trolley moveable in tracks on the bridge at right angles to the tracks on the bridge. The trolley carries a mast assembly for engaging, raising, and lowering a nuclear-reactor component assembly involved in the refueling. The mast includes an elongated member for engaging control-rod and thimble plug assembly and a gripper for raising fuel assemblies. The elongated member is moveable upwardly or downwardly.A TV camera and a light source and reflector are mounted on the gripper assembly at the lower end of the mast assembly. The source and reflector illuminate a selected part of the fuel assembly which is to be transferred and the camera is directed to this part so as to pick up an image of this part. The cooperative TV-receiver monitor on the console on the trolley is provided with cross hairs. The mast assembly is set by aligning the cross hairs with images of the heads of selected bolts on the image of the reactor component assembly.
