ABSTRACT OF THE DISCLOSURE A module for the storage of nuclear waste packages from a nuclear power plant is disclosed comprising a concrete precast container with sidewalls and a bottom, a concrete precast lid removably disposed on upper edges of the sidewalls to close the container, and a cylindrical one-piece seamless liner abutting and covering the interior surface of the container. The liner is provided with anchor means formed integral with the liner that extend along outside surfaces of the liner sidewalls and bottom wall, and the anchor means is embedded within the concrete precast sidewalls on the container. The anchor means is provided by a plurality of ribs which can be T-shaped or dovetail shaped in cross-sectional area and may extend either longitudinally or circumferentially about the liner. The module is manufactured by the first forming a one-piece seamless liner including the ribs on its outer surfaces, placing the liner in a mold for the module, and thereafter pouring concrete into the module mold to completely fill the space between the liner and the mold for embedding the ribs within the concrete. The integrally formed liner provides and additional barrier for nuclear wastes that is advantageously devoid of seams or weld joints. The manufacturing method of the invention insures a perfect, gapless fit between the liner and the concrete module.
