  1. 1. Phenyl Trifluoromethyl Sulfone as Diluent in a Grouped ActiNide EXtraction Process

    Författare :Jenny Halleröd; Chalmers tekniska högskola; []
    Nyckelord :Solvent Extraction; FS-13; CyMe4-BTBP and TBP; GANEX;

    Sammanfattning : The demand for electricity and electrical energy is very high both in Sweden and in the other industrialised countries in the world. An upgrade of the nuclear power plants, including recycling of the used nuclear fuel, would make nuclear power a sustainable energy option. Over the years different types of nuclear reactors have been developed. LÄS MER

  3. 2. Development of a Solvent Extraction Process for Group Actinide Recovery from Used Nuclear Fuel

    Författare :Emma Aneheim; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Partitioning; Solvent Extraction; Fission Products; TBP; BTBP; GANEX;

    Sammanfattning : When uranium is used as fuel in nuclear reactors it both undergoes neutron induced fission as well as neutron capture. Through successive neutron capture and beta decay transuranic elements such as neptunium, plutonium, americium and curium are produced in substantial amounts. LÄS MER

  4. 3. On a Solvent Extraction System for Recycling Used Nuclear Fuel with CyMe4-BTBP and TBP as Extracting Agents

    Författare :Jenny Halleröd; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solvent Extraction; CyMe4-BTBP; FS-13; GANEX; TBP;

    Sammanfattning : In Sweden, as well as in many other countries worldwide, the demand for electricity and electrical energy is high. One solution to satisfy this demand in the long term could be to upgrade the nuclear power plants, including recycling of used nuclear fuel, to Generation IV. LÄS MER

  5. 4. CHALMEX FS-13 investigations for process implementation

    Författare :Thea Lyseid Authen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmutation; SolventExtraction; CHALMEX; Partitioning; GANEX;

    Sammanfattning : From successive neutron absorption by uranium in nuclear reactors, transuranic elements such as neptunium, plutonium, americium and curium are produced. These elements are the main reason for the long-lived, highly radiotoxic and heat-producing nature of spent nuclear fuel. LÄS MER

  7. 5. Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on bis-triazine-bipyrididine (BTBP)-class Ligands

    Författare :Elin Löfström Engdahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Used nuclear fuel; Density; Solvent; Extraction vs. time; BTBP; GANEX; Liquid-Liquid Extraction; Interfacial tension; Diluent;

    Sammanfattning : Used nuclear fuel taken directly from a reactor is radiotoxic for mankind and its environment for a long time. One of the major contributions to the long time radiotoxicity is the presence of a group of elements called the actinides. LÄS MER
