  • Patent number: 11024436
    Abstract: Waste capsules for disposal of radioactive materials, including weapons grade plutonium, are made entirely from rock, such as, but not limited to, granite; wherein a cap of such a waste capsule is seamlessly rock welded to a lower body portion of the given waste capsule, to form the given waste capsule, with the radioactive materials inside of a cavity of that waste capsule. The weld region is homogenous with both the cap and the lower body portion. A cooling system may be used during or after rock welding. The sealed and rock welded waste capsule, with the internal radioactive materials, is then loaded into a wellbore system that extends into a deep geological rock repository, thousands of feet below the Earth's surface, such that the waste capsule comes to rest in a wellbore located within the deep geological rock repository. The waste capsule may include insulating material in the cavity.

  • Patent number: 10988390
    Abstract: A reactor system for reacting liquid phase chemical species in a liquid includes a reactor vessel for containing the liquid phase and a gas phase. The reactor vessel can have a gas injection port, a gas exit port, and a liquid-gas interface location within the reactor vessel. A pulsed discharge cathode and anode are provided for creating a pulsed discharge electric field at the liquid-gas interface location. A pulsed discharge power supply delivers a pulsed power input to the pulsed discharge cathode and anode, and thereby creates a plasma comprising ions at the liquid-gas interface location. A secondary electric field source is provided for directing a secondary electric field transverse to the liquid-gas interface. The secondary electric field will drive some of the ions from the gas phase into the liquid phase to react with the liquid phase chemical species. A method for reacting a liquid phase chemical species is also disclosed.
