摘要： The cables containing the electrical wiring for the control rod mechanisms and the instrumentation for a nuclear reactor are brought by the shortest path to cable support racks affixed to the enclosure surrounding the control mechanisms hereinafter referred to as the mechanism enclosure. The cables are supported on a series of such support racks until they terminate in receptacles mounted on the floor of a platform attached to the mechanism enclosure on the side facing the refueling storage area for the mechanisms, vessel head and internals. An elongated frame-like cable tray is attached to the platform by a hinged joint while the other end is supported on flanged guide rollers. The cables are looped onto the cable tray at its hinged end and are supported in tiers thereon by separator plates and anchor clamps. At the other end of the tray, the cables are hung in large loops and are connected to plugs in the floor of the instrument room. The cables accordingly need not be disconnected from the mechanisms when moving same for refueling.

摘要： For the purpose of reducing the time required for removal and replacement of a reactor pressure vessel closure head, each stud utilized for securing the head on the pressure vessel is provided with modified breechblock threads at its lower end. After being unloaded, the studs are rotated 60* for disengagement from corresponding threads in a flange at the top of the pressure vessel and can be lifted out of the stud holes in the vessel flange along with the head when it is removed from the vessel. Each stud is provided with an individual hydraulic tensioning device, mounted on top of the head flange.

摘要： A nuclear reactor is disclosed wherein hydraulic drive mechanisms are provided to vary the location of a plurality of neutron absorbing control elements associated with selected fuel assemblies. Each fuel assembly comprises a fixed array of commingled and spaced fuel pins and guide tubes. Each selected assembly has a plurality of individually movable two-position control elements which are coupled to drive mechanisms which operate to telescope the control elements within their associated guide tubes. The control elements are situated such that they can be withdrawn into and removed with the upper support structure for refueling.

摘要： A nuclear reactor in which the control rods are held withdrawn or retracted from the fuel by a permanent magnet during refueling. The reactor includes a missile shield which restrains the control rod units from being ejected upwardly during normal operation of the reactor. During refueling the shield is retracted. During normal operation the control rods, when withdrawn, are held by an electromagnet whose coil may be readily deenergized for rod insertion at any time. During refueling the retraction of the shield causes a permanent magnet to replace the electromagnet core.

摘要： There is disclosed the combination of a nuclear reactor with a missile shield which also affords protection in the event of a seismic disturbance. The shield is massive plate of steel or the like with ribs and is mounted above, and connected to, the upper package of the reactor. The plate has hole through which projections from the housings of the retracting mechanism cluster for the control rods pass. In the event of a seismic disturbance the movement of the mechanism clusters is limited by the restraint exerted by the shield plate on the projections. In addition the shield is retractable from the upper package by operation of hydraulic pistons and when retraced locks the rod retracting mechanisms for a refueling operation.

摘要： A nuclear reactor has control rods which may be operated between control positions and retracted positions by linearly-movable elements or drive means. In the retracted position, a control rod or a group of control rods may be retained by latches, the lower tips of which enter a groove in a linearly-movable element or drive means. The latches are movable between a released position and a restraining position. The latches are made of magnetic steel and are maintained in the restraining position by permanent magnet means which are operable between a coupled magnetic position wherein the drive means is maintained in the restraining condition and a decoupled position wherein the latches may release the associated drive means. Such operation of the magnet is in response to movement of a missile shield associated with the nuclear reactor.

摘要： In order to reduce the time required for removal and replacement of a reactor vessel closure head, previously used studs for securing the closure head are replaced with a reduced member of larger diameter bolts located in radial slots in vessel and head flanges. All bolts are provided with individual hydraulic tensioning and tilting devices mounted on the head flange. The devices are operated simultaneously to preload the bolts and to actuate the bolts and the devices to an inclined position to permit the head to be removed when the tension load on the bolts is released.

After being detensioned, the studs are rotated 60* for disengagement from corresponding threads in a flange at the top of the pressure vessel and are lifted out of the stud holes when the head is removed. The studs are tensioned and detensioned by a plurality of portable hydraulic stud tensioning devices or tensioners which are attached to the upper ends of the studs by the modified breechblock threads at the upper ends of the studs. The tensioners are carried by a separate hoist system mounted on the closure head for the vessel.
