Zusammenfassung:PURPOSE: A top portion placement assembly of nuclear fuel aggregate is provided to facilitate the assembly and disassembly process of the nuclear fuel aggregate at a long distance. CONSTITUTION: A top portion placement(100) has an internal space. One end of an insert(200) is combined to a guide tube. The other end of the insert is accepted to the inside of the top portion placement. A locking member(300) is inserted between the top portion placement and the insert in order to fix the insert on the top portion placement. A plurality of protrusions(220) is formed on the outer circumference of the insert. The protrusions are settled in a supporting jaw(340) formed on the inner circumference of the locking member. A supporting part(230) is formed on the outer circumference of the lower part of the insert in order to restrict the movement of insert in the upper direction.
