摘要： An integrated head assembly for a nuclear reactor pressure vessel includes a closure head with CRDM assemblies extending upwardly from the head. A CRDM seismic support disposed above the closure head provides lateral support for the CRDM assemblies. The seismic support also has air flow holes which communicate with the interior of a shroud enclosing the CRDMs and extending upwardly from the closure head to the seismic support. The shroud has an air port in direct air flow communication with the surrounding atmosphere so that the closure head, shroud and seismic support define an air flow passageway directly communicating with the surrounding atmosphere via the air port and without the extensive ductwork and, therefore, with substantially less power.
摘要翻译：用于核反应堆压力容器的集成头组件包括具有从头部向上延伸的CRDM组件的封闭头。设置在封闭头上方的CRDM地震支架为CRDM组件提供横向支撑。地震支架还具有气流孔，该气流孔与包围CRDM的护罩的内部连通，并从闭合头向上延伸到地震支座。护罩具有与周围空气直接空气流连通的空气口，使得封闭头，护罩和地震支架限定通过空气口直接与周围大气连通的空气流动通道，并且没有广泛的管道系统，因此，大大减少功率。

摘要： A temporary support structure for supporting a lower internals assembly above the reactor vessel during inspection and/or maintenance thereof. A support bracket is bolted to the reactor vessel flange at the vessel head stud closure holes. A pivotally mounted arm, upon the top surface of which the internals rest, is attached at one end to the support bracket and projects radially inwardly therefrom. A compliant foot depends from the bottom of the opposite end of the arm and engages the vessel internals support ledge to provide a secure support structure for the internals assembly. An alignment bracket on the arm aligns the internals with the support. Four such structures are installed around the circumference of the vessel flange while the internals are within the reactor vessel. The structure allows the lower internals to be quickly removed from the interior of the reactor vessel and placed on the temporary supports. By supporting the internals above the vessel from the vessel flange, the lower internals remain essentially completely submerged by the shielding medium.

摘要： Elongated coolant pumps suspended under steam generators within containment in a power plant with limited access space, are removed and replaced by an elongated maintenance cart with an elongated opening along one side in which the motor is received. Rollers support the cart for conveying the elongated motor in an upright position out from under the steam generator and onto an elevator. The elevator is lowered to transfer support of the cart and motor through trunnions to saddles straddling the elevator for rotation of the cart to a generally horizontal position. The elevator then raises the horizontally disposed cart carrying the motor to a higher floor where it is rolled off the elevator and out through the auxiliary equipment hatch.

摘要： Service apparatus is provided for a large inverted canned motor pump installed above a floor and beneath a large steam generator in a fossil or nuclear power plant with limited access space and with limited access time at least in the case of nuclear power plants. The canned motor pump has a pump casing and a depending motor having a flange secured to a pump casing flange by a plurality of tensioned studs with tightened nuts.The service apparatus includes a maintenance cart having a height greater than the height of the motor casing beneath the motor flange and further having a generally U-shaped frame with an open vertical side that permits the cart to be moved horizontally such that the cart frame can be moved under the pump casing to surround the depending motor.Three electromechanical actuators are supported by the cart frame and each has a downwardly extending translating arm engageable with respective motor lugs near the bottom of the motor. The translating arms are operated to support, raise and lower the motor with its axis vertical or at an incline to the vertical. The motor is supported on top of the cart frame prior to raising the motor to its installed position and after the motor has been released from its installed position and lowered to the cart.A work platform is provided on top of the cart by a plate welded to the top of the framework platform and a removable platform section extending across the open side of the frame. A personnel platform is provided on the cart art an elevation below the work platform. The personnel platform includes a swing down section on the bight cart side, two fixed sections on the two leg sides of the cart and a removable section on the open cart side. Rollers are provided on the bottom of the cart frame to facilitate horizontal cart movement along the floor.

摘要： A steam generator wrapper closure and a method of installing the same includes a plug member (108) which includes a large diameter portion (110) and a small diameter portion (112) with an annular shoulder portion (114) defined therebetween. A locking pawl (124) is rotatably mounted upon the plug (108) through means of its shaft (122). A pawl shaft extension rod (154) and a handle (150) are utilized to manipulate the pawl (124) and the plug (108) from a position external to the steam generator outer shell (16). The axis of the pawl shaft (122) is radially offset with repect to the axis of the plug (108), and the diametrical extent of the pawl (124) is less than that of the small diameter portion (112) of the plug (108). In this manner, when the pawl (124) is rotated to a first position within which the pawl (124) is disposed within the circumferential boundary of the small diameter portion (112) of the plug (108), the pawl (124) and small diameter plug portion (112) may be inserted within the wrapper penetration (104) until the shoulder portion (114) of the plug (108) engages the exterior surface (118) of the wrapper (46). The pawl (124) may then be rotated to a diametrically opposite position within which the pawl (124) engages the interior surface (138) of the wrapper (46) thereby lockingly retaining the plug member (108) within the wrapper penetration (104).
