  4. 22. Development of a Solvent Extraction Process for Group Actinide Recovery from Used Nuclear Fuel

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

    Abstract : 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. READ MORE

  5. 23. Radiolytic Degradation of BTBP type Molecules for Treatment of Used Nuclear Fuel by Solvent Extraction

    Author : Anna Fermvik; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transmutation; lanthanides; degradation; solvent extraction; actinides; radiolysis; BTBP; partitioning;

    Abstract : Nuclear fuel that has been discharged from nuclear reactors is highly radiotoxic and must be kept isolated from the biosphere for very long time periods. This requires an advanced final repository. One way to decrease the long-term radiotoxicity and thermal load of the used fuel is Partitioning and Transmutation (P&T). READ MORE
