摘要： Apparatus comprising a seal connector ist disclosed for sealingly connecting flow channels in the core support plate with flow channels in fuel assemblies for use in a spectral shift pressurized water nuclear reactor in which spectral shift is obtained by displacing a portion of the light water in the core with deuterium oxide or a combination of deuterium oxide and light water or various gases such as helium during the initial state of reactor operation to harden the nuclear spectrum and thereby reduce excess reactivity and increase the production of fissile materials. The seal connectors provide a sealed flow channel for introducing the deuterium oxide to the fuel assemblies during the early stages of reactor operation and for reintroducing the light water into the fuel assemblies during the later stages of reactor operation.

摘要： @ A nuclear reactor fuel assembly having an improved top nozzle subassembly with a hold-down device incorporated therewithin to prevent the force of the upward coolant flow from lifting the fuel assembly into damaging contact with the upper core support plate, while allowing for changes in fuel assembly length due to thermal expansion. The construction of the fuel assembly is such that its top surface can be placed in direct contact with the upper core plate. Thermal expansion of the components of the fuel assembly in the upward direction are accommodated within the top nozzle subassembly.

摘要： A nuclear reactor with control-rod clusters (49) movable into and out of its core (27) has a calandria structure (39) above the area of movement of the control-rod clusters (49). The coolant flow from the core (27) remains axially upward in the area (37) of movement of the control-rod clusters (49). Radial coolant flow occurs only through the calandria (39) above the control-rod cluster guide structure. The calandria (39) has tubes (58) between upper and lower supports (56, 54) which receive the drive rods (101) for the control-rod clusters (49) so as to protect the drive rods (101) from the transverse flow of coolant within the calandria (39).

摘要： © Preferably, the pressurized reactor coolant is utilized to raise the drive rod into contact with and to pivot the latching mechanism so as to allow the drive rod to pass the latching mechanism. The pressure in the housing may then be equalized which allows the drive rod to move downwardly into contact with the latching mechanism but to hold the shaft in a raised position with respect to the reactor core. Once again, the reactor coolant pressure may be utilized to raise the drive rod and thus pivot the latching mechanism so that the drive rod passes above the latching mechanism. Again, the mechanism pressure can be equalized which allows the drive rod to fall and pass by the latching mechanism so that the drive rod approaches the reactor core.
摘要翻译：优选地，加压反应堆冷却剂用于升高驱动杆与闭锁机构接触和枢转，以便允许驱动杆通过闭锁机构。然后可以将壳体中的压力相等，这允许驱动杆向下移动以与闭锁机构接触，但是将轴保持在相对于反应堆芯的升高位置。再次，可以利用反应堆冷却剂压力来升高驱动杆并因此使闩锁机构枢转，使得驱动杆通过闩锁机构上方。再次，机构压力可以相等，这允许驱动杆落下并通过闩锁机构，使得驱动杆接近反应堆芯。

摘要： A fluid pump powered by an integral canned motor includes a housing (4) having a cylindrical passage (6) extending therethrough. A sealed annular stator (10) is mounted around the housing. An impeller assembly (16) is rotatably mounted in the passage in the housing. The impeller assembly includes an axial flow impeller (18) and a sealed rotor (20) mounted around the periphery of the impeller. Bearings, including thrust bearings (24), are mounted between the periphery of the impeller assembly and the housing. A radial flow auxiliary impeller (28) may be mounted on the impeller assembly to create a radial flow of water from the cylindrical passage in the housing to a peripheral fluid circulation channel (26) between the impeller assembly and the housing. The auxiliary flow impeller pressurizes the peripheral fluid circulation channel.

摘要： A pivoted pad bearing assembly of the Kingsbury type provides for leveling of bearing pads arranged in a circular array utilizing hydrostatic pressure rather than mechanical links. The leveling device is in the form of a hydraulic bearing support module having a variable volume hydraulic chamber. Pipe segments connect each hydraulic chamber to form a closed circuit and the circuit is completely filled with hydraulic fluid. Thereby, equal force will be exerted upon each pad at all times so that all pads will operate at an equal thrust load. The bearing assembly has particularly useful application in an integral motor submersible propulsor as a large diameter thrust bearing housed within an outer shroud of the propulsor at both upstream and downstream ends of a rotor mounted about the periphery of a propeller of the propulsor. By placing the thrust bearing within the shroud, greater thrust bearing surface areas can be obtained to handle larger thrust. By using hydrostatic leveling, the noise associated with mechanical linkages is avoided, and the size and weight of the bearing assembly can advantageously be reduced.
摘要翻译： Kingsbury型枢轴支承轴承组件提供了利用流体静力学压力而不是机械连杆以圆形阵列布置的轴承瓦平整。平整装置是具有可变容积液压室的液压轴承支撑模块的形式。管段连接每个液压室以形成一个闭合回路，并且电路完全充满液压油。因此，所有的焊盘将始终施加相等的力，使得所有焊盘将以相等的推力载荷工作。轴承组件在整体马达潜水推进器中具有特别有用的应用，作为大直径推力轴承，该大直径推力轴承容纳在围绕推进器的螺旋桨的周边安装的转子的上游和下游端处的推进器的外护罩内。通过将止推轴承放置在护罩内，可以获得更大的推力轴承表面积来处理较大的推力。通过使用静水平调节，避免了与机械连接相关联的噪声，并且可以有利地减小轴承组件的尺寸和重量。

The steam generator (80) has relatively small diameter manway openings (170) for providing access to the interior of the steam generator including the inside surface (300) of each nozzle (280, 290), the manway openings (170) having a diameter substantially less than the inside diameter of each nozzle (280, 290). The apparatus includes a bracket (410) having an outside surface (420) for matingly sealingly engaging the inside surface (300) of the nozzle (280, 290). The bracket (410) also has a plurality of openings (440) longitudinally therethrough and a plurality of slots (425) transversely therein in communication with each opening (440). A plurality of unitary plugs (450) sized to pass through the manway opening (170) are matingly sealingly disposed in each opening (440) of the bracket (410) for sealingly plugging each opening (440). Each plug (450) includes a plurality of arms (620) operable to engage the slots (425) of the bracket (410) for connecting each plug (450) to the bracket (410), so that the nozzle (280, 290) is sealed as the plugs (450) seal the openings (440) and are connected to the bracket (410).
