摘要： The present invention relates to a transport basket for defective spent nuclear fuel of a heavy water reactor and, more particularly, to a transport basket for defective spent nuclear fuel of a heavy water reactor that can reduce the burden of a personnel when handling spent nuclear fuel in a test facility by minimizing a storage space and maximizing a thickness such that only a predetermined amount of spent nuclear fuel for soundness evaluation in the test facility can be transported. To this end, provided is a transport basket for defective spent nuclear fuel of a heavy water reactor, comprising: a basket body having a storage space and an internal support that partitions the storage space; a fuel pocket that is installed on one side of each storage space partitioned through the internal support and is installed so as to be rotatable toward the other side of the storage space, and has a detachable groove open in an upward direction such that a fuel case containing the spent nuclear fuel can be detached therefrom; and a cover that opens and closes the storage space of the basket body and is screwed to the basket body.

摘要： The present invention relates to a cutting apparatus for a fuel basket containing spent nuclear fuel in a heavy water reactor and, more particularly, to a cutting apparatus for a fuel basket containing spent nuclear fuel in a heavy water reactor, which enables the spent nuclear fuel contained inside to be withdrawn without damage through welding bead cutting rather than through-cutting, and enables cutting chips generated during a cutting operation to be neatly and easily recovered without scattering on the bottom of a storage tank. To this end, the present invention provides a cutting apparatus for a fuel basket containing spent nuclear fuel in a heavy water reactor, the apparatus comprising: a base; a vertical support installed on one side of the base; a rotary table installed to reciprocate between the one side and the other side of the base, and to rotate horizontally on the base; a horizontal support installed to extend from the upper end of the vertical support toward the rotary table in a horizontal direction; a side cutting means installed on the vertical support and protruding toward the rotary table so as to cut a side welding bead of a fuel basket mounted on the rotary table; and an upper cutting means installed on the horizontal support and protruding toward the rotary table so as to cut an upper welding bead of the fuel basket mounted on the rotary table.
