PURPOSE: To make fuel elements with a small cross section surface area movable in a magazine with a large cross section surface area to cut the already irradiated fuel elements by installing a cavity. a hollow. a blank a movable blade, and a lock means in a pusher. CONSTITUTION: Fuel elements are arranged horizontally in a magazine to cut the elements and an end plate 2 is brought into contact with a movable blade 19 and moved forward in a desiring distance by a single driving means 20 which affects the whole body of a pusher. When the end part of a cavity 15 comes closer to a clamp 8, a blank 28 of the pusher can pass and backward movement of an auxiliary clamp 8 in a hollow 18 is induced, Release of a lock means 27 between the driving means 20 and the pusher main body 12 is controlled, the fuel elements are moved forward, and only the driving means 20 to stop cutting affects the blade 19. Consequently, fuel elements with a small cross-section surface area can be made movable in a magazine with a large cross section surface area.
