Permanent isolation system for hazardous waste in a geological repository
A geological repository adapted for permanent isolation of hazardous waste and a method permanently isolating hazardous waste from the biosphere are disclosed. The geological repository includes a near surface void having side walls and a floor disposed in a geologically stable formation. The geologically stable formation is selected to have low permeability, thereby providing a barrier to ingress of groundwater. The repository is provided with a ramp to the floor of the void for movement of hazardous material transporting vehicles and an inflatable cover configured to provide a barrier between the void and the surface environment. The inflatable cover has a flexible top layer adapted to extend over the entire area of said void and outer edge elements which form a plurality of skirt flaps disposed along its perimeter. An anchor is used to secure said skirt flaps to a surface perimeter of said void so as to maintain a seal between the inflatable cover and said void. One or more sealable access hatches are provided in the inflatable cover to allow access of personnel and hazardous material transporting vehicles between said void and the surface environment. The repository is also provided with a fan for inflating the inflatable cover.
