ABSTRACT:
A system for disposing of hazardous waste, such as nuclear waste, underground which provides the drilling of a wellbore down into a level of a underground bed of salt, for example, and forming a horizontal borehole through the salt bed next, drilling a plurality of radial wells off of the horizontal well to a predetermined length of each radial well extending outward from the horizontal wellbore; lowering a quantity of nuclear wastes contained within a specially designed pre-packed liner at the end of a drill string, into each of the radial wells drilled off of the horizontal wellbore; providing a packer at the entrance to each of the radial wells for packing off the borehole of each of the radial wells to completely isolate the nuclear wastes within the radial wellbore; retrieving the drillstring from the horizontal wellbore; cementing the entire length of the horizontal wellbore so as to further isolate each of the radial wells containing the spent nuclear waste; and capping off the vertical wellbore on the surface so as to provide a fully sealed nuclear waste disposal facility with nuclear wastes disposed ir each of the radial wellbores, each of the bores sealed off from one another.
