The invention discloses a structure of a storage container for a spherical nuclear fuel element, and relates to the field of storage of dangerous goods. The storage container for the spherical nuclear fuel element comprises a container shell, a container cover, a neutron absorbing layer and a bundling element drum group. The storage container for the spherical nuclear fuel element is characterized in that the container shell is formed by connecting a container drum body and a container base plate; an internal end opening in the upper end of the container drum body is provided with a top plate; the container cover is connected with the top plate through a stud; the neutron absorbing layer comprises a cavity structure arranged outside the container drum body and neutron absorbing materials filling in the cavity; the bundling element drum group is arranged inside the container drum body and comprises a plurality of cylinders which are arranged regularly and are used for loading the spherical nuclear fuel element. The storage container for the spherical nuclear fuel element solves the problem that a container which is specially suitable for the storage of the spherical nuclear fuel element and is easy to operate is absent.
