  • The chemistry of acetohydroxamic acid related to nuclear fuel reprocessing

    Creator:
    Matteson, Brent Searle
    Abstract:
    Used Nuclear Fuel (UNF) contains transuranic (TRU) elements and numerous fission products as a result of the uranium fission process and neutron activation that occur in commercial light water power reactors. Recent environmental and nuclear proliferation concerns have spawned the development of advanced reprocessing techniques to close the nuclear fuel...

  • Investigation of mixed N,O-donor dipicolinamide derivative ligands for use in nuclear fuel separations

    Creator:
    Lapka, Joseph
    Abstract:
    In this work, three isomeric forms of N, N'-diethyl, N, N'-ditolyldipicolinamide (EtTDPA) were synthesized. The elements thorium through americium, which make up a significant portion of the actinides in used nuclear fuel (with the exception of curium), and two fission products, molybdenum and technetium, were tested for their ability to...

  • Aqueous complexation of citric acid and DTPA with selected trivalent and tetravalent f-elements

    Creator:
    Brown, M. Alex
    Abstract:
    Carboxylic acids have played an important role in the field of actinide (An) and lanthanide (Ln) separations and the reprocessing of irradiated nuclear fuel. Recent bench-scale experiments have demonstrated that 3-carboxy-3-hydroxypentanedioic acid (citric acid) is a promising aqueous complexant that can effectively aid in the separation of transition metals from...
