A basket for a cask for transporting nuclear fuel elements, said basket comprising a plurality of sleeve members, each of said sleeve members having interior cross-section dimensions for receiving a nuclear fuel assembly such that the assembly is restrained from lateral movement within said sleeve member, a plurality of apertured disk members, means for axially aligning the apertures in said disk members, means for maintaining said disk members in fixed spaced relationship to form a disk assembly, comprising an array of disks, the aligned apertures of said disks being adapted to receive said sleeve members and maintain them in fixed spaced relationship, first and second apertured end caps, the apertures of which are stepped to form first and second different cross-sectional aperture dimensions and forming a shoulder therebetween, the first cross-sectional dimensions of each aperture being adapted to receive the end of a sleeve, so that said end bears against said shoulder and the second cross-sectional dimension of each aperture being substantially the same as the internal cross-section of said sleeve, and means for maintaining said first end cap to one end of the disk assemblies and said second end cap to the other end of said disk assembly with the apertures in said end caps axially aligned with the apertures in said disks.
