    Sammanfattning : Shortages of fossil fuel and other political movements contributed to the nuclear energy “renaissance”.Nuclear energy, however, is not free of challenges, one of them being nuclear waste management. LÄS MER

  3. 3. Extraction Properties of some Nitrogen-Containing Extractants and Determination of Nitrate Complex Formation for Lanthanides and Selected Actinides Using Solvent Extraction

    Författare :Sofie Andersson; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actinides; solvent extraction; separation; lanthanides; nitrate complex formation;

    Sammanfattning : Partitioning and transmutation of spent nuclear fuel will reduce the amount of waste and its radiotoxicity in a long-term perspective. At the same time the energy content of the spent nuclear fuel can be used more efficiently by recycling of uranium and plutonium and by using energy from the transmutation reactor. LÄS MER
