  • Patent number: 10717660
    Abstract: A vessel for removing radionuclides from a liquid. The vessel comprises a shielded housing comprising an outer shell and an inner shell disposed within the outer shell. The housing defines an ion exchange chamber between the inner and outer shells. The vessel also comprises an inlet fluidly coupled with the ion exchange chamber, the inlet being configured for fluid communication with a source of the liquid, and an outlet fluidly coupled with the ion exchange chamber, the outlet being configured for fluid communication with a destination of the liquid. The vessel further comprises a first fluid passage extending between an exterior of the vessel and the inner shell and a second fluid passage extending between the exterior of the vessel and the inner shell.

  • Patent number: 10580542
    Abstract: One aspect of the invention provides a system for treating wastestream, particularly a liquid or aqueous radwaste, for safe disposal and, in final processing, converting it into one or both forms including an aqueous form for safe discharge to the environment and a solidified form for safe disposal. Another aspect provides the capacity to employ a step where a specific target element strategy can be set up synchronizing sorbent substance choices and multiple recycle options to remove target substances from wastestream as a part of its Sorption or Powder Sorbent Isotopic Reduction step (II). Other steps cooperate with Sorption step (II) including Oxidation (I) to inactivate or destroy existing chelants, Solid-Liquid separation (III), and Selective Ion Exchange (IV) to deliver the wastestream to final processing.

  • Patent number: 9896351
    Abstract: A vessel for treatment of radioactive liquid. The vessel comprises a shielded housing defining an ion exchange chamber therein. The ion exchange chamber is configured to receive ion exchange media in its interior between an interior top surface and an interior bottom surface. The vessel further comprises an inlet diffuser disposed in the ion exchange chamber proximate the bottom surface and an outlet collection header disposed in the ion exchange chamber proximate the top surface. Also, the vessel comprises a process inlet in fluid communication with the inlet diffuser and a process outlet in fluid communication with the outlet collection header.

  • Patent number: 9218897
    Abstract: A vessel for both treatment of radioactive wastewater and disposal of radioactive waste contained therein. The vessel comprises a main vessel structure including a shell formed of a metal material and a liner integrally coupled to the interior surface of the shell. The liner is preferably formed of a plastic material, such as high density polyethylene. Waste treatment equipment for treatment of the radioactive wastewater is provided within the shell. Ion exchange resin is typically located in the main vessel structure which, when spent, constitutes the radioactive waste which is subject to disposal. The vessel is preferably configured to function as a High Integrity Container (HIC).
