Patent attributes
Systems and methods for long-term disposal of nuclear and/or radioactive waste materials, in liquid, solid, and/or other physical forms, using an array deeply located human-made caverns (caverns), wherein the array of caverns are within a deep geologic rock formation and below a grid pattern on a surface of the Earth. Each cavern is made from a substantially vertical wellbore, by drilling and under reaming operations upon a distal portion of the substantially vertical wellbore. At least some of the caverns may be connected by intersecting substantially lateral wellbores that may facilitate injection of protective materials into the caverns that are so intersected. The nuclear and/or radioactive waste may be preprocessed from original surface storage site(s), transported, temporarily surface stored, and then finally further processed at a selected wellsite before injection into a given of the subterranean deep caverns within the deep geologic rock formation.
