  • Systems and methods for treating material
    Patent number: 8867692
    Abstract: Systems for treating material are provided that can include a vessel defining a volume, at least one conduit coupled to the vessel and in fluid communication with the vessel, material within the vessel, and NF3 material within the conduit. Methods for fluorinating material are provided that can include exposing the material to NF3 to fluorinate at least a portion of the material. Methods for separating components of material are also provided that can include exposing the material to NF3 to at least partially fluorinate a portion of the material, and separating at least one fluorinated component of the fluorinated portion from the material. The materials exposed to the NF3 material can include but are not limited to one or more of U, Ru, Rh, Mo, Tc, Np, Pu, Sb, Ag, Am, Sn, Zr, Cs, Th, and/or Rb.
    Type: Grant

  • Separation of iodine from mercury containing scrubbing solutions
    Patent number: 4162206
    Abstract: Radioactive iodines can be recovered from a nitric acid scrub solution containing mercuric nitrate by passing a current through the scrub solution to react the iodine with the mercuric nitrate to form mercuric iodate which precipitates out. The mercuric iodate can then be reacted to recover the radioiodine for further processing into a form suitable for long-term storage and to recover the mercury for recycling.
