摘要： An annular seal ring between a reactor pressure vessel and a containment wall is disposed in an annular expansion gap therebetween, having a support ring and inner and outer upwardly extending cylindrical sections. The inner cylindrical section is disposed below a flange on the reactor and has a flexible seal therebetween, while the outer cylindrical section terminates substantially parallel and spaced from a shelf in the containment wall with a flexible seal therebetween. The annular seal ring is supported by radial support beams, while support rods depending from the support ring position neutron shielding material in the annular expansion gap. Manways and ports provide access to the gap and thermal insulation is provided below the neutron shielding material to direct cooling air from the annular gap up through opened manway and port.

摘要： A system for transferring fuel assemblies in a nuclear reactor includes a load control system which compares the current load to the more restrictive of fixed overload and underload limits, and instantaneous overload and underload limits continuously calculated from a running average of the measured load. Operation of the refueling machine is terminated if any of these limits are exceeded. The system also accommdates for changes in buoyancy and tension loading applied by spring loaded reels for pneumatic hoses and electrical cables servicing the gripper which engages the fuel assembly as the mast supporting the fuel assembly is raised and lowered in the pool of shielding water covering the reactor core. The current and recent suspended load measurements are displayed relative to the fixed and instantaneous overload and underload limits on a graphic display along with speed and other pertinent data.

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 high preload quick operating closure for a pressure vessel (17) comprises a vessel opening or nozzle (19) having a port flange (20) with an upper surface (23), which has a wall (26) affixed thereto, the wall (26) having one or more circumferentially spaced holes (32), the combination of the wall (26) and port flange (20) forming a well (29), and a vessel head (27) forming a closure for the port flange. A plurality of wedge assemblies (30) secured to the wall (26) at holes (32), comprising hydraulically operated cylinders (39) operably connected to wedges (33) which slidably engage a tapered surface (40) of the vessel head (27) creating a larger sealing force between the head (27) and the flange (20) to seal the pressure vessel (17) with an enormous preload. The closure incorporates a control system (50) with two independent safety features to prevent the closure device from opening when the pressure vessel ( 17) is pressurized.

摘要： A position sensing mechanism, for use with a nuclear fuel transfer system which employs an underwater cart having a pivotable container to receive fuel assemblies, employs mechanical elements below water and a cable which carries movement of the mechanical elements to a switch assembly at a dry location. The mechanical elements include an anchor element which is affixed to an upender mechanism, which selectively moves the container between horizontal and upended positions when the cart is located at a fuel transfer station, and a feeler mechanism which is displaced by the cart. The feeler mechanism includes a pivotably mounted swing arm and one or more pulleys. The cable is attached to the anchor elements and is guided by the pulleys. The switch assembly includes a further pulley having cams to actuate microswitches when the cable is displaced by the anchor element and feeler mechanism. A temperature compensator is spliced into the cable to keep its length constant despite temperature variations.

摘要： A system for mounting material directing impellers to the table of a centrifugal impact crusher includes an upstanding mounting plate having a slot extending through it which opens out of its top surface. An impeller has a rearwardly facing stob extending from it which slidably fits within the slot. A nub, which does not fit through the slot, is attached to the extremity of the stob and the stob is sized such that the nub and the rear surface of the impeller interact with the mounting plate to prevent the impeller from moving relative to the mounting plate in either circumferential direction. The sides of the slot are angled radially outwardly as they extend downwardly toward the table.

摘要： System provides a positive verification of the presence of a reactor coolant leak in the reactor vessel head area, identifies its location, and enables its size to be determined. A series of video cameras 28 strategically placed about the shroud 16 on the vessel head 13 provide complete viewing coverage. Variable intensity halogen lamps 46, 47 provide illumination for the area to be inspected. The equipment is specially adapted for use in a highly irradiated environment. The system 25 allows for inspection of the reactor vessel head area without the need for shutting down the plant.

摘要： A nuclear reactor containment arrangement has a permanent cavity ring seal extending across an annular expansion gap between a reactor pressure vessel and a containment wall to provide a water tight seal therebetween. The annular ring seal has a support ring with an inner downwardly extending cylindrical section resting on the reactor flange and an outer downwardly extending cylindrical section resting on a shelf in the containment wall. A vertically extending, L-shaped, seal extends between an inner end of the support ring while a vertically extending, L-shaped, seal extends between the outer cylindrical section and the containment wall shelf. Neutron shielding material is suspended, by support rods, within the annular expansion gap while thermal insulation is provided therebelow. Manways and ports in the support ring are sealed by hatches and provide access to the annular expansion gap and, while open, provide for flow of cooling air from the annular expansion gap through the support ring.
