    • 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.
    • 一种核部件转移装置,其将屏蔽罐结合到常规核燃料加注机的桅杆设计中。 一个可移动的桅杆望远镜在一个固定的桅杆内,该桅杆连接到一个桥上进行横向定位。 该罐允许添加屏蔽件,该屏蔽件随着可移动桅杆的移动而定位,而无需额外的机动组件来在核部件移动期间展开屏蔽件。 随着可移动桅杆提升核部件,核部件被吸入屏蔽罐中。 然后将核部件放入也装有屏蔽罐的转移车中。 转移是在不暴露核组件的情况下完成的,导致完全屏蔽运动。

    • Refueling of a nuclear reactor (40) includes removing a fuel assembly (10). The removal method includes lowering a lifting tool (80) of a crane (44) onto a top of the fuel assembly. The lowered lifting tool including a plurality of downwardly extending elements (82) that surround and vertically overlap a portion (74) of a control rod assembly (70) extending above the top of the fuel assembly. The downwardly extending elements are locked with corresponding mating features (26) at the top of the fuel assembly to connect the lifting tool with the fuel assembly. The connected fuel assembly is moved into a spent fuel pool (42) using the crane, and the lifting tool is disconnected from the top of the fuel assembly by unlocking the downwardly extending elements from the corresponding mating features at the top of the fuel assembly.
    • 核反应堆(40)的加油包括移除燃料组件(10)。 拆卸方法包括将起重机(44)的提升工具(80)降低到燃料组件的顶部上。 所述降低的提升工具包括多个向下延伸的元件(82),所述多个向下延伸的元件围绕并垂直地重叠在燃料组件的顶部上方延伸的控制杆组件(70)的部分(74)。 向下延伸的元件在燃料组件的顶部与对应的配合特征(26)锁定,以将提升工具与燃料组件相连接。 使用起重机将连接的燃料组件移动到乏燃料池(42)中,并且通过从燃料组件的顶部处的对应配合特征解锁向下延伸的元件,提升工具从燃料组件的顶部断开。
