Patent number: 11270805Abstract: A system and method to safely isolate mobile radioactive material during an emergency includes a borehole located in close proximity and at a depth sufficient to safely isolate the material and a man-made vertical-oriented gravity fracture located at the bottom end of the borehole. During an emergency, the mobile radioactive material enters the borehole and then passes from there into the gravity fracture. The mobile radioactive material may have sufficient density to further propagate the fracture vertically downward or a dense slurry or fluid could be mixed with the mobile radioactive material.Type: GrantFiled: October 29, 2018Date of Patent: March 8, 2022Assignee: Grand Abyss, LLCInventors: Leonid N. Germanovich, Lawrence C. Murdoch, Marvin Robinowitz

Patent number: 10629315Abstract: A system and method of disposing nuclear waste and other hazardous waste includes means for, and the steps of, blending a waste stream, which includes either a radioactive waste or a hazardous waste (or both), with a liquid and, optionally, a solid material to produce a dense fluid and pumping the dense fluid into a tubing string of an injection boring. The dense fluid then exits a perforation in a casing of the injection boring and enters a fracture in a rock strata, where it continues to propagate downward until it reaches an immobilization point. The dense fluid may be a slurry formed by a metal and a cross-linked polymer gel or hydrated clay slurry. The metal can be one that has a melting temperature less than the temperature at the bottom of the injection boring. The solid material could also be other nuclear waste or a radionuclide.Type: GrantFiled: July 23, 2018Date of Patent: April 21, 2020Assignee: Grand Abyss, LLCInventors: Leonid N. Germanovich, Lawrence C. Murdoch, Marvin Robinowitz

Patent number: 10115489Abstract: A system and method to safely isolate mobile radioactive material during an emergency includes a borehole located in close proximity and at a depth sufficient to safely isolate the material. An already- or pre-prepared vertical-oriented gravity fracture is located at the bottom end of the borehole, with the mobile radioactive material entering the gravity fracture during the emergency. A dense slurry or fluid could be mixed with the mobile radioactive material to create and propagate the gravity fracture as the radioactive material is being disposed of.Type: GrantFiled: September 12, 2016Date of Patent: October 30, 2018Assignee: Grand Abyss, LLCInventors: Leonid N. Germanovich, Lawrence C. Murdoch, Marvin Robinowitz

Publication number: 20180075935Abstract: A method for in-situ subsurface isolation of nuclear material at a nuclear power or nuclear waste facility during an emergency includes a borehole located in close proximity and at a depth sufficient to safely isolate the radioactive material. A gravity fracture in the surrounding rock formation is located at the bottom end of the borehole, with the radioactive material entering the gravity fracture. A dense slurry or fluid could be mixed with the radioactive material to create and propagate the gravity fracture.Type: ApplicationFiled: September 12, 2016Publication date: March 15, 2018Inventors: Leonid N.
