Claims

[Scope of utility model registration request]

(1) A cylindrical basket that holds cut pieces of spent nuclear fuel inside and is charged vertically into a melting device, and is a porous outer tube with a bottom member having a central hole at the lower end. a porous inner tube installed coaxially within the outer tube so that its lower end is located a predetermined distance above the bottom member; a cylindrical upper half; A lower half consisting of a plurality of vertical bars hanging from the lower end, a ring-shaped bottom seat fixed to the lower end of the lower half, and formed on the outer periphery of the boundary between the ten-half part and the lower half, The cylindrical upper half is loosely fitted to the lower end of the inner tube, and the lower half is a discharging member that is inserted through the center hole of the bottom member. A basket for a spent nuclear fuel melting device, comprising: a tubular member;

(2) The basket for a spent nuclear fuel melting device according to claim 1, wherein the upper surface of the bottom member is a slope that slopes downward toward the center hole.

(3) The lower surface of the engagement member provided on the discharge tubular member is an inclined surface having the same slope as the bottom member at the lower end of the outer tube. Basket of spent nuclear fuel melting equipment described.

(4) Any one of claims 1 to 3 of the utility model registration claim, characterized in that the upper surface of the bottom seat provided at the lower end of the discharge tubular member is a slope that slopes downward in the radial direction. A basket for the spent nuclear fuel melting device according to item 1.
