Zusammenfassung:The present invention relates to an apparatus for removing a lower end fitting body of a spent nuclear fuel skeleton. The apparatus includes a tool guide assemble which comprises a tool guide combined with a bolt connecting a guide pipe and the lower end fitting body mounted on the upper part of a lower fitting body assembly. Therefore, a worker operates the tool guide instead of the bolt by a wrench tool. Thereby, the bolt is more easily released so that the lower end fitting body can be separated. 본 발명은 사용후 핵연료 골격체의 하단고정체 분리 장치에 관한 것으로, 하단고정체 어셈블리의 상부에 안착되면 하단고정체와 안내관을 연결하는 볼트에 결합되는 툴가이드가 구비된 툴가이드 어셈블리를 포함한다. 따라서, 작업자는 렌치툴로 볼트가 아닌 툴가이드를 조작함으로써 한층 용이하게 볼트를 해제하여 하단고정체를 분리할 수 있다.
