摘要： The invention relates to the field of nuclear technology, in particular, to the disposal of spent long-length elements of a nuclear reactor. The invention reduces the complexity and time required to splice long-length elements and minimizes dose loads on attendants. The method of splicing long-length elements of a nuclear reactor into fragments involves placement of long-length elements inside the container and subsequent cutting. The long element is lowered into the container to its full height and cut on the level of the upper edge of the container with the separation from it of a fragment equal to the height of the container, then the upper part of the long-length element remaining after cutting is lowered inside the container to its full height and the cutting of the long-length element into fragments is repeated until it is fully spliced.
