摘要： A nuclear reactor containment arrangement has a permanent cavity ring seal extending across an annular expansion gap (25) between a reactor pressure vessel (35) and a containment wall (15) to provide a water tight seal therebetween. The annular ring seal has a support ring (33) with an inner downwardly extending cylindrical section (35) resting on the reactor flange (27) and an outer downwardly extending cylindrical section (37) resting on a shelf (21) in the containment wall. A vertically extending, L-shaped, seal (49) extends between an inner end of the support ring while a vertically extending, L-shaped, seal (51) extends between the outer cylindrical section and the containment wall shelf (21). Neutron shielding material (75) is suspended, by support rods (77), within the annular expansion gap (25) 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.

摘要： Apparatus for transferring the fuel assemblies and other component assemblies including control-rod assemblies, thimble-plug assemblies, poison assemblies and the like during refueling of a nuclear reactor. The apparatus includes an outer mast for guiding and protecting the component assemblies which are transferred, an inner mast movable vertically within the guiding mast. The inner mast has grippers for engaging and lifting or lowering fuel assemblies. The outer mast has internal grooved rollers along its length guiding the inner mast. An elongated tube movably disposed within the inner mast has a grapple for engaging and lifting or lowering the component assemblies other than the fuel assemblies. An actuator rod is provided which locks the grapple to the component assemblies.

摘要： A remotely operated device which attaches to an existing internals lifting rig to safely lift and transport nuclear reactor internals structures. The device includes a grapple assembly uniquely formed to maximize the effective bearing surface of an annular shoulder (32) disposed on the grapple assembly to engage the internals structure (12). The annular shoulder (32) comprises a first outer diameter (36), the annular shoulder defining a second outer diameter (40) disposed thereabove. The grapple assembly comprises a plurality of fingers (76) circumferentially disposed about an actuator rod (20) which has a diameter (26) essentially equal to a first inner diameter of the grapple assembly. The lower end of the grapple assembly has a second inner diameter smaller than the first and axially adjacent to the annular shoulder. In order to maximize the bearing surface, the fingers of the grapple assembly are formed such that the first inner and outer diameters are machined with respect to a first axis, whereas the second inner and outer diameters are formed with respect to a second axis parallel to the first. These machining axes are offset from each other by a distance which is equal to the desired amount of radial expansion of the fingers. This uniquely formed grapple device thus has a bearing surface 30 to 40 percent greater than that achieved by prior art devices.

摘要： Refueling apparatus for a nuclear reactor including a bridge (57) and a trolley (59). The bridge (57) is moveable on tracks (62, 63) along the containment (55) of the pit (53) in which the reactor is immersed in water and the trolley (59) is moveable in tracks (121, 123) on the bridge (57) at right angles to the tracks (62, 63) on the bridge (57). The trolley (59) carries a mast assembly (61) for engaging and raising and lowering a nuclear-reactor component assembly involved in the refueling.
The bridge (57), trolley (59) and mast assembly (61) each has a pulse generator which produces pulses in accordance with the movement of each for identification of the position of each. Means are provided for automatic re-calibration of the position identifying system.
Also, means are provided for containing supply lines for the mast (61) so as to permit undisturbed movement of the- mast relative to the trolley (59).

摘要： An annular seal ring between a reactor pressure vessel (35) and a containment wall (15) is disposed in an annular expansion gap (25) therebetween, having a support ring (33) and inner and outer upwardly extending cylindrical sections (35,37). The inner cylindrical section (35) is disposed below a flange (27) on the reactor and has a flexible seal (39) therebetween, while the outer cylindrical section (37) terminates substantially parallel and spaced from a shelf (21) in the containment wall with a flexible seal (41) therebetween. The annular seal ring is supported by radial support beams (79), while support rods (91) depending from the support ring position neutron shielding material in the annular expansion gap. Manways and ports (151) provide access to the gap and thermal insulation (135) is provided below the neutron shielding material (89) to direct cooling air from the annular gap up through opened manway and port.

摘要： The responses of a nuclear reactor refueling machine to commands from a detachable control console (48) are simulated in a portable simulator to allow operation of the console for testing and operator training with the console removed from the machine. The simulator (52) connected to the console includes a single-pulse generator (70) driven by a single three-phase A-C motor (68) to simulate movement of the refueling machine bridge (2), trolley (4) and hoist (6). The portable simulator contains relays to simulate engagement and disengagement of fuel assembly and control rod cluster grippers and a device for coupling portions of the refueling machine mast to the hoist.
