Abstract: The invention relates to a container for receiving radioactive waste materials, in particular for receiving spent fuel elements, comprising a container casing, a container base which is connected to the container casing, and at least one container cover. The container cover has at least One locking recess which is arranged its the edge region on the upper face of the cover. At least one locking element is arranged or at least one locking element can be arranged in the locking recess. The locking element has at feast one formfitting protrusion which is oriented in the direction of the container easing and which engages into a complementary formfitting recess of the container casing in the locked state of the container cover. The formfitting recess is arranged in the edge region of the container casing on the cover side.

Abstract: A container for holding radioactive waste has a side wall, a floor connected to a lower end of the side wall, and a cover. A set of side-wall formations is provided at an upper end of the side wall and on an inner surface of the side wall, and a set of cover-edge formations is distributed around an outer edge of the cover and fittable with the side-wall formations. Thus, as a result of the interfitting of cover-edge formations with the side-wall formations, the cover can be or is fixedly connected to the side wall without welds.
