Abstract
Systems, methods, processes, and/or steps for the long-term disposal of high-level nuclear and radioactive waste, along with other radioactive waste forms, is done within deep salt formation(s) of predetermined characteristics. Waste may be emplaced within a given deep salt formation and after emplacement, creep of that deep salt formation around the deposited waste may entirely entomb that emplaced waste safely for geologic time periods. To emplace the waste, wellbore(s) may be drilled from the Earth's terrestrial surface into the given deep salt formation and then either a mostly horizontal wellbore may be formed within the given deep salt formation and/or a human-made cavern may be formed down and within the given deep salt formation. After emplacement, creep of the deep salt formation will destroy the initial boundaries of the horizontal wellbore and/or of the human-made cavern. This creep sealing process may occur over relatively short time periods.
