    Sammanfattning : In the pursuit of safer, more environmentally friendly and sustainable forms of energy production for our ever growing demands, a type of nuclear reactor cooled by liquid metal instead of water is under development. Specific to this type of reactor are special forms of corrosion of the material that encapsulates the fuel pins in the reactor core, called Fuel-Clad Chemical Interaction (FCCI) or Fission Product-induced Liquid Metal Embrittlement (FPLME).

  3. 27. Redox Chemistry in Radiation Induced Dissolution of Spent Nuclear Fuel : from Elementary Reactions to Predictive Modeling

    Författare :Olivia Roth; Mats Jonsson; David W. Shoesmith; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear chemistry; Kärnkemi;

    Sammanfattning : The focus of this doctoral thesis is the redox chemistry involved in radiation induced oxidative dissolution of spent nuclear fuel and UO2 (as a model substance for spent nuclear fuel). It is shown that two electron oxidants are more efficient than one electron oxidants in oxidative dissolution of UO2 at low oxidant concentrations. LÄS MER

  7. 30. Physical Characterization of Actinide Particles - A Study on Novel Techniques for Radiological and Nuclear Safeguard Investigations

    Författare :Ylva Ranebo; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; plutonium oxide particles; secondary ion mass spectrometry; uranium oxide particles; hot particles; vibrating orifice aerosol generator; scanning electron microscopy; nuclear safeguards;

    Sammanfattning : This thesis presents a study of advanced analytical techniques, for the characterization of actinide particles originating from the non-peaceful use of nuclear technology and from international inspections of the nuclear fuel cycle associated with non-proliferation agreements. The thesis is based on five papers, which will be referred to by Paper I-V in the text. LÄS MER
