An improved waste disposal site for the above-ground disposal of low-level nuclear waste as disclosed herein. The disposal site is formed from at least three individual waste-containing tumuli, wherein each tumuli includes a central raised portion bordered by a sloping side portion. Two of the tumuli are constructed at ground level with adjoining side portions, and a third above-ground tumulus is constructed over the mutually adjoining side portions of the ground-level tumuli. Both the floor and the roof of each tumulus includes a layer of water-shedding material such as compacted clay, and the clay layer in the roofs of the two ground-level tumuli form the compacted clay layer of the floor of the third above-ground tumulus. Each tumulus further includes a shield wall, preferably formed from a solid array of low-level handleable nuclear wate packages. The provision of such a shield wall protects workers from potentially harmful radiation when higher-level, non-handleable packages of nuclear waste are stacked in the center of the tumulus.

A method of constructing a site for the above-ground disposal of radioactive wastes, comprising the steps of a. constructing a deformable floor for a first tumulus that includes a deformable layer of water-shedding material; b. constructing a shield wall means on said floor capable of blocking radiation from said wastes; c. depositing an array of packages containing radioactive wastes over said floor and behind said shield wall; d. constructing a deformable roof over the array of waste packages which includes a deformable layer of water-shedding material, and an intrusion barrier beneath the deformable layer of water-shedding material, said barrier being constructed by overlaying the array of waste packages with a plurality of flexibly interlocking structures; e. constructing a second tumulus in accordance with steps a-d which is close enough to the first tumulus so that the deformable layers in the roofs of the first and second tumuli adjoin one another; and f. constructing a third tumulus over the roofs of the first and second tumuli in accordance with steps a-d wherein the mutually adjoining, deformable layers of water-shedding material in said roofs provide the deformable layer of water-shedding material of the floor of the third tumulus.
