摘要： A nuclear component transfer device that incorporates a shielded canister into the mast design of a conventional nuclear refueling machine. A moveable mast telescopes within a stationary mast which is attached to a bridge for lateral positioning. The canister allows for the addition of shielding that is positioned with the movement of the moveable mast without additional motorized components to deploy the shielding during nuclear component movement. The nuclear component is drawn up into the shielded canister as the moveable mast lifts the nuclear component. The nuclear component is then placed into a transfer cart that is also fitted with a shielded canister. The transfer is made without exposing the nuclear components resulting in completely shield movement.

摘要： Methods and apparatus for moving fuel bundles in a reactor pressure vessel (RPV) of a nuclear reactor are described. In one embodiment of the apparatus, a support tube facilitates the positioning of a multiple channeled magazine within the RPV, especially at locations adjacent fuel bundles. In the one embodiment, the support tube extends in the reactor pressure vessel into the area above the top guide. A magazine assembly is coupled to the support tube, and includes a magazine having a plurality of fuel bundle receiving channels. The magazine extends from the support tube so that it is adjacent the fuel bundles and the top guide. Grapples extend through the magazine channels, engage the fuel bundles, and retract the bundles into the magazine channels. The magazine and support tube, and thus the bundles, are then moved.

摘要： A reactor refueling mechanism includes a bridge, a trolley on the bridge, and an elevator on the trolley, with the elevator including a mast with a grapple at the lower end thereof. The bridge spans a reactor core and is rotatable therearound, with the trolley being translatable over the bridge. The elevator is also rotatable on the trolley, and the mast is vertically movable for positioning of the grapple. The combined movement capability of the mechanism allows the shuffling of fuel bundles between cells in the reactor core, and the accurate placement of square fuel bundles in complementary square cells in the core.

摘要： The crane operated lifting apparatus for safely gripping and holding obje (11) includes a plurality of movable pawls (3) which enter into a groove, aperture, or bore (14) of an object (11) which is to be transported. To move the pawls (3), a driving member (4) is provided which is displaceable in a basic body (1). The lifting apparatus also includes comprises two holding members (2,5) the first of which is firmly attached to the basic body (1) while the second one is connected to the driving member (4) for a tilting or pivoting motion. Thus, the hook of a crane may selectively grasp either one of the two holding members (2,5) or both of them (2,5) together, and it may also selectively swing the second holding member, (5). In this manner it is possible to have all the functions, such as locking, unlocking, and conveying, accomplished by the hook of a crane alone.

摘要： A coupling device between a nuclear reactor control rod and an actuating mechanism has a gripper body having resilient gripping fingers, belonging to the mechanism and, on the bar, a terminal pommel for engagement by the fingers and a shoulder directed towards the pommel. The coupling device comprises an additional member, such as a sleeve, movable with respect to the gripper body between a position in which it allows resilient fingers to be released from the pommel and another position in which it locks the resilient fingers onto the pommel. The sleeve has an end face bearing on the shoulder of the pommel. A prestressed spring exerts a force tending to move the sleeve away from the fingers so as to hold the end face of the sleeve firmly applied against the shoulder when the fingers are locked on the pommel.

摘要： The proposed nuclear reactor comprises fuel assemblies whose heads are shaped as prisms and provided with an internal hollow for the working member of the gripping means to grip and handle the fuel assembly. The gripping means is accommodated in a guide member of a refuelling device having an end face shaped as a truncated cone whose vertex is directed towards the head of a fuel assembly being handled. Recesses are provided in the end faces of the fuel assembly heads. The number of recesses is equal to that of fuel assemblies adjacent to the fuel assembly being handled. The recesses are arranged symmetrically with respect to the face edges of the fuel assembly heads. The sides of the recesses next to the recess which is adjacent to the recess of the fuel assembly being handled and facing the fuel assembly being handled all form parts of the surface of a truncated cone whose axis is matched with the longitudinal axis of the fuel assembly being handled. The diameter of the lesser base of the truncated cone of the guide member is greater than the diameter of the lesser base of the truncated cone partially formed by the sides of the recesses facing the fuel assembly being handled, but less than the diameter of its greater base.
