摘要:
A joint structure between a top nozzle and a guide thimble of a nuclear fuel assembly and, more particularly, a structure for joining an inner-extension tube, the top nozzle and the guide thimble. When an inner-extension tube head, which is provided as a means for facilitating removal of the top nozzle of the nuclear fuel assembly from the guide thimble, is removed from an inner-extension tube body to separate the top nozzle from the nuclear fuel assembly, the inner-extension tube body is prevented from undesirably rotating, so that the guide thimble and the inner-extension tube body can maintain the joined state.
摘要(中):
核燃料组件的顶部喷嘴和导向套管之间的接合结构,更具体地,用于连接内部延伸管,顶部喷嘴和导向套管的结构。 当作为用于便于从引导套管移除核燃料组件的顶部喷嘴的装置提供的内部延伸管头从内部延伸管体移除以将顶部喷嘴与核燃料组件分开时 内部延伸管体被防止不期望地旋转,使得导向套管和内延伸管体可以保持接合状态。
